The experts of Extramarks have made this question series so that students can solve questions regularly. They have collated these questions from several sources such as the textbook exercises, CBSE sample papers, CBSE past years’ question papers and important reference books. They have solved these questions too. Thus, the Important Questions Class 6 Maths Chapter 14 will help students to score better in exams. The important questions are
Question 1. Construct, with the help of a ruler and compasses, the angles of the following measures:
(i) 60°
(ii) 30°
(iii) 90°
(iv) 120°
(v) 45°
(vi) 135°
Answer:
(i) 60 degree
The following steps should be followed to construct an angle of 60 degrees.
(a) Firstly, Draw a line l and then mark a point P on it. Then take point P as a centre, and with the convenient radius, then draw an arc of a circle such that it intersects the line l at point Q.
(b) Now, Take Q as the centre point and with the same radius as before, then draw an arc intersecting the previously drawn arc, and name it point R.
(c) Join the points and form PR. PR is the required ray that makes 60 with line l.
(ii) 30 degrees
The following steps should be followed to construct an angle of 30 degrees.
(a) Draw a line l and mark a point P on the line. Now By taking point P as the centre point and with the convenient radius, draw an arc of a circle such that it intersects the line l at point Q.
(b) Now, Take point Q as the centre point and with the same radius as before, draw an arc which intersects the previously drawn arc at point R.
(c) Now, By taking the points Q and R as the centres and with a radius of more than the 1 / 2 RQ, draw the arcs such that they can intersect each other at point S. Join these ray PS, which is the required ray making 30 degrees with the line l.
(iii) 90 degree
The following steps should be followed to construct an angle of measure 90 degrees.
(a) Draw a line l and mark a point P on the line. Then take point P as the centre, and with the convenient radius, also draw an arc of a circle such that it intersects at line l at point Q.
(b) Now Take the point Q as the centre, and with the same radius as before, draw an arc that intersects the previously drawn arc at the point R
(c) By taking the point R as a centre and with the help of the same radius as before, draw an arc intersecting the arc at S as shown in the given figure

(e) Join and form PT, which is the required ray making 90 degrees with the line l.
(iv) 120 degrees
The following steps should be followed to construct an angle of measure 120 degrees.
(a) Draw a line l and mark a point P on it. Then taking point P as a centre and with the convenient radius, then draw an arc of a circle such that it intersects the line l at point Q.
(b) By taking point Q as the centre point and with the same radius taken as before, draw an arc which intersects the previously drawn arc at point R.
(c) Take the point R as the centre point and with the same radius taken as before, draw an arc such that it intersects the arc at point S, as shown in the given figure.
(d) Join the point PS, which is the required ray making 120 degrees with the line l
(v) 45 degrees
The following steps should be followed to construct an angle of measure 45 degrees.
(a) Draw a line l and mark a point P on it. Then take point P as a centre, and with the convenient radius, now draw an arc of a circle such that it intersects the line l at point Q.
(b) Take the point Q as a centre and with the same radius taken as before, draw an arc intersecting the previously drawn arc at the point R
(c) By taking point R as a centre and with the same radius taken as before, draw an arc such that it intersects the arc at point S, as shown in the given figure.
(d) Take the points R and S as centres and draw the arcs of the same radius such that they intersect each other at point T
(e) Join the points and form PT. Let this intersect the major arc at point U.
(f) Now take the points Q and U as centres and draw arcs with a radius of more than 1 / 2 QU to intersect each other at point V. Then Join PV.
PV is the required ray making 45 degrees with the line.
(vi) 135 degrees
The following steps should be followed to construct an angle of measure 135 degrees.
(i) Draw a line as l and mark a point P on it. Then taking P as the centre and with a convenient radius, draw a semicircle which then intersects the line l at points Q and R, respectively.
(ii) By taking the point R as the centre and with the same radius as before, draw an arc which intersects the previously drawn arc at point S
(iii) Taking the point S as the centre point and with the same radius as before, draw an arc so that it intersects the arc at point T, as shown in the given figure
(iv) Now, Take the points S and T as the centre point, then draw arcs of the same radius to intersect each other at point U.
(v) Join the points to form PU. Let this intersect the arc at point V. Now take the points Q and V as the centres, and with a radius of more than 1 / 2 QV, draw arcs to intersect each other at point W.
(vi) Join the pints to form PW, which is the required ray making 1350 with the line l
Question 2. Draw an angle of 70 degrees. Make a copy of it with the help of only a straight edge and compasses.
Answer 2:
The following steps should be followed to construct an angle of measure 70degree with its copy.
(i) Draw a line and name it l, and then mark a point O on it. Now place the centre of the protractor at point O and the zero edge along line l.
(ii) Mark point A at an angle to measure 70 degrees. Join both points to form OA. Now OA is the ray making 70 degrees with the line l. With point O as the centre, draw an arc of a convenient radius in the interior at a 70degree angle. Let this intersect both rays of angle 70 at points B and C, respectively
(iii) Draw a line as M and mark a point P on the line. Again draw an arc with the same radius as before, with P as the centre. Let it cut the line m at point D
(iv) Now, Adjust the compasses up to the length of BC. With this radius, draw an arc taking point D as the centre, which then intersects the previously drawn arc at point E.
(v) Join these points to form PE. Here the PE is the required ray which makes the same angle of measuring 70 degrees with the line m
Question 3. Draw an angle of 40 degrees. Also, Copy its supplementary angle.
Answer 3:
The following steps should be followed to construct an angle of measure 45 degrees and a copy of its supplementary angle.
(i) Draw a line segment and then mark a point O on the line segment. Place the centre of the protractor at point O and the zero edge along the line segment.
(ii) Mark a point as A at an angle of measure 40 degrees. Join these points to form OA. Here OA is the required ray making 40 degrees with ∠POA, is the supplementary angle of 400
(iii) With point O as the centre point, draw an arc of the convenient radius in the interior of the angle ∠POA. Let this intersects both rays of ∠POA at points B and C, respectively.
(iv) Now Draw a line m and mark a point S on the line. Again draw an arc by taking point S as a centre with the same radius that is used before. Let it cut the line m at point T.
(v) Now adjust the compasses up to the length of ray BC. Taking point T as a centre, draw an arc with this radius which will then intersect the previously drawn arc at point R.
(vi) Join the ray RS. Here that RS is the required ray which makes the same angle with the line m, as they are supplementary of 400 [which is 140 degrees]
Now Draw a line l and a point X on it. Through X, draw a line segment XY¯¯¯¯¯¯¯¯ perpendicular to the line l. Now draw a perpendicular to the ray XY at Y. (use ruler and compasses)
Solution :
Step 1. Given a point X on a line, l.
Step 2. With X as a centre and a convenient radius, construct a part circle (arc) intersecting line l at two points, A and B.
Step 3. With these points A and B as centres and a radius greater than AX, construct two arcs which cut each other at Y.
