RS Aggarwal Solutions Class 8 Maths Chapter 15 Quadrilaterals – Overview

RS Aggarwal Solutions Class 8 Maths Chapter 15 Quadrilaterals is based on qudilaterals. You must know about the following things before you start studying:

• Quadrilaterals are polygons that have a total of four sides and four corners.

• There are six different types of quadrilaterals which are square, rectangle, parallelogram, rhombus, kite, and trapezium. All these six figures have four vertices and four sides enclosing four angles.

• The sum of all the four angles of a quadrilateral comes to a total of 360 degrees. This value gets derived from the polygon’s interior angles equation, i.e., (n – 2) × 180.

Sides and Angles Of A Quadilateral

• Usually quadilaterls have sides with different angles and lengths, but in some cases, some of the sides and angles are equal to each other. Eg: square has all sides and angles are equal to each other, whereas in a rectangle only opposite sides are equal and all angles are equal to each other. 

Formulae For Area Of Quadilateral

• Area of a Square – (side)2

• Area of a Rectangle –  Length x Breadth

• Area of a Parallelogram – Base x Height

• Area of a Trapezium – { (Sum of two opposite sides / 2) x Height }

• Area of a Rhombus – Product of two diagonals / 2

• Area of a Kite – Product of two diagonals / 2

Perimeter Of A Quadilateral

Formula for Perimtere of every quadilateral is same, i.e., sum of all sides.
