A Polygon is a straightforward closed curve formed entirely of straight lines, according to the NCERT Solutions For Class 8 Maths Chapter 3 Exercise 3.3. As a result, a Polygon with four sides, four angles, and four vertices is said to be a Quadrilateral. Before moving on to learning Quadrilaterals, this chapter begins by exposing youngsters to several very crucial ideas. The categorization of Polygons based on sides, the study of Diagonals, Concave, Convex, Regular, and Irregular Polygons, as well as the Angle Sum Property, are some of the subjects covered in this course. Every concept has been explained clearly in the NCERT Solutions For Class 8 Maths Chapter 3 Exercise 3.3.
The key ideas presented in this chapter include the following: 3.1 Introduction 3.2 Polygons 3.2.1 Classification of Polygons 3.2.2 Diagonals 3.2.3 Convex and Concave Polygons 3.2.4 Regular and Irregular Polygons 3.2.5 Angle Sum Property 3.3 Sum of the Measures of the Exterior Angles of a Polygon 3.4 Kinds of Quadrilaterals 3.4.1 Trapezium 3.4.2 Kite 3.4.3 Parallelogram 3.4.4 Elements of a Parallelogram 3.4.5 Angles of Parallelogram 3.4.6 Diagonals of a parallelogram 3.5 Some special Parallelograms 3.5.1 Rhombus 3.5.2 A Rectangle 3.5.3 A Square.
What is a Quadrilateral?
A Quadrilateral is a flat shape with four edges and four corners, also known as vertices. The Quadrilateral has angles at each of its four vertices, or corners. The angles at the vertices of a Quadrilateral ABCD are ∠A, ∠B, ∠C, and ∠D. A quadrilateral has the following sides: AB, BC, CD, and DA. The diagonals are obtained by joining the opposing vertices of the Quadrilateral. The diagonals of the Quadrilateral ABCD are shown in the figure below as AC and BD. All such definitions and questions are solved in the NCERT Solutions For Class 8 Maths Chapter 3 Exercise 3.3.
Based on the measurements of the angles and side lengths, Quadrilateral kinds are identified. All of these quadrilateral designs have four sides because the term “quad” implies “four,” and their combined angles total 360 degrees. These are the several kinds of Quadrilaterals:
Another approach to different kinds of Quadrilaterals is as follows:
- Convex Quadrilaterals: A figure that entirely encloses both of a Quadrilateral’s diagonals.
- Concave Quadrilaterals: One or more of the diagonals extends partially or completely outside of the picture.
- Quadrilaterals that cross: A Quadrilateral in which the two non-adjacent sides do not intersect is not a simple Quadrilateral. Self-intersecting or crossed Quadrilaterals are the names for these Quadrilaterals.
All the topics and subtopics are discussed in the NCERT Solutions For Class 8 Maths Chapter 3 Exercise 3.3. To know more about the Chapter students should access the NCERT Solutions For Class 8 Maths Chapter 3 Exercise 3.3.

Q.1 Given a parallelogram ABCD. Complete each statement along with the definition or property used.
1. AD = ……
2. ∠ DCB = ……
3. OC = ……
4. m ∠DAB + m ∠CDA = …..
1. AD = BC
(Opposite sides are of equal length in a parallelogram.)
2. ∠ DCB = ∠ DAB
(Opposite angles are equal in measure.)
3. OC = OA
(In a parallelogram, diagonals bisect each other)
4. m ∠DAB + m ∠CDA = 180°
(In a parallelogram, adjacent angles are supplementary to each other.)
Q.2 Consider the following parallelograms. Find the values of the unknowns x, y, z.
Q.3 Can a quadrilateral ABCD be a parallelogram if
(i) ∠D + ∠B = 180°?
(ii) AB = DC = 8 cm, AD = 4 cm and BC = 4.4 cm?
(iii) ∠A = 70° and ∠C = 65°?
A parallelogram has opposite sides equal and parallel. The opposite angles are also equal. The adjacent angles are supplementary.
- So, if ∠D + ∠B = 180°, a quadrilateral ABCD may or may not be a parallelogram as all the other conditions of the parallelogram should also be fulfilled by a quadrilateral ABCD.
- In a parallelogram the opposite sides should be of equal length. Here, AB is equal to CD but AD is not equal to BC. Hence, ABCD is not a parallelogram.
- In a parallelogram the opposite angles are of equal length. Here, ∠A is not equal to ∠C. Hence, ABCD is not a parallelogram.
Q.4 Draw a rough figure of a quadrilateral that is not a parallelogram but has exactly two opposite angles of equal measure.
Here, ABCD is a quadrilateral that is not a parallelogram but ∠B=∠D.
Q.5 The measures of two adjacent angles of a parallelogram are in the ratio 3 : 2. Find the measure of each of the angles of the parallelogram.
Thus, the measures of the angles of the parallelogram are 108°, 72°, 108°, and 72°.
Q.6 Two adjacent angles of a parallelogram have equal measure. Find the measure of each of the angles of the parallelogram.
In a parallelogram the adjacent angles are supplementary
Q.7 The adjacent figure HOPE is a parallelogram. Find the angle measures x, y and z. State the properties you use to find them.
Q.8 The following figures GUNS and RUNS are parallelograms . Find x and y. (Lengths are in cm)
(i) We know that, the lengths of opposite sides of a parallelogram are equal to each other.
Therefore, GU = SN and SG =NU
Hence, the measures of x and y are 6 cm and 9 cm.
(ii) We know that the diagonals of a parallelogram bisect each other.
Hence, the measures of x and y are 3 cm and 13 cm.
In the above figure both RISK and CLUE are parallelograms. Find the value of x.
Q.10 Explain how this figure is a trapezium. Which of its two sides are parallel?
Here, ∠NML + ∠MLK = 180°
Hence, NM||LK and ML is a transversal.(If a transversal intersects the two given lines such that the sum of the angles on the same side of transversal is 180º, then the given two lines will be parallel to each other.)
Therefore, KLMN is a trapezium as it has one pair of parallel lines.
