More about Class 8 Maths Chapter 3

What is a regular polygon? State the name of a regular polygon of: (a) 3 sides (b) 4 sides (c) 6 sides

A regular polygon: A polygon having all sides of equal length and the interior angles of equal size is known as regular polygon.
(i) 3 sides
Polygon having three sides is called a triangle.

(ii) 4 sides
Polygon having four sides is called a quadrilateral.

(iii) 6 sides
Polygon having six sides is called a hexagon.

How many sides does a regular polygon have, if the measure of an exterior angle is 24 degree?

Let number of sides be n.
Sum of exterior angles of a regular polygon = 360
Number of sides = n = 360/24 = 15
Hence, the regular polygon has 15 sides.

In Chapter 3 Understanding Quadrilaterals, we will learn about plane surface and plane figures, different types of polygons like Triangles, Quadrilaterals, Pentagon, Hexagon, Heptagon, etc. Number of diagonals in each polygon, a brief description about CONVEX and CONCAVE polygons. Regular and irregular polygons having 3, 4, 5 and 6. Angle sum property of triangle and the questions based on the same fact to find the missing term. Questions based on sum of measure of exterior angles and questions related to Trapezium, Parallelogram, Kite to find the missing side or angle.

How To Prepare Class 8 Maths Chapter 3

There are exercises based on the properties of different types of quadrilaterals in this lesson. Just as all the sides and all the angles of the square are equal, the opposite sides of the rectangle are equal, the opposite angle and the diagonal are also equal. Quadrilateral and rectangle have the difference of angles and diagonals. If the diagonals of a rhombus are equal, then it is square. Every angle of a square is a right angle. All the questions in chapter 3 of 8th Maths are mainly based on the properties of polygons.
