Chapter 3- Understanding Quadrilaterals

The Study of Quadrilaterals!

Quadrilaterals are simply the four-sided figures. However, these have different kinds according to their properties. The CBSE curriculum of class 8th includes the study of quadrilaterals in math. The students learn about polygons, their properties, solutions of the exterior angles, and different kinds of quadrilaterals as well.

With the course provided by ScoreX™, you can complete the study of the CBSE class 8 Maths chapter 3.

What is the format of this chapter course?

The course of the Class 8 Maths Ch-3 Understanding Quadrilaterals includes topics that you have in your school book.

1. Polygons

Polygons are the plane figures that have three or more straight sides. The topic helps you learn following concepts:

·         Classification of polygons

·         Diagonals

·         Convex and concave polygons

·         Regular and irregular polygons

·         Angle Sum Property

2. Sum of the Measures of the Exterior Angles of a Polygon

The sum of the measures of exterior angles of a polygon is studied. The formula and rules are provided to find the missing angles in a polygon.

3. Kinds of Quadrilaterals

Quadrilaterals have different types depending upon the number of sides, and shapes. You learn about:

·         Trapezium

·         Kite

·         Parallelogram

·         Elements of a parallelogram

·         Angles of a parallelogram

·         Diagonals of a parallelogram

4. Some Special Parallelogram

A parallelogram is a four-sided shape having parallel opposite sides. The topic helps you know about following types of parallelograms:

·         Rhombus

·         A rectangle

·         A square
