## RS Aggarwal Solutions Class 7 Maths Chapter 20 Ex 20.4 – Overview

In the fourth exercise of RS Aggarwal Solutions Class 7 Maths Chapter 20, there is a total of 12 questions. The emphasis of such questions is going to be on performing the calculation of the equilateral triangle and right-angle triangle.

### Right Angled Triangle

*“The square of the hypotenuse side is equivalent to the sum of the squares of the base value and the height.”*

### Right Angle Triangle Properties

- In the “Right Angle Triangle”, one of the angles will always be equal to 90 degrees or the right angle.
- In the “Right Angle Triangle “, the hypotenuse side is the side that is opposite to the 90 degrees angle.
- In the “Right Angle Triangle”, the hypotenuse is always on the longest side.
- In the “Right Angle Triangle”, the sum of the remaining two angles will always be equal to 90 degrees.
- In the “Right Angle Triangle”, the neighbouring sides are called the base and the perpendicular.
- In the “Right Angle Triangle”, its area is equivalent to half of the product of the right angle triangle’s neighbouring sides i.e., Area ( Right Angle Triangle ) = ( 1 / 2 ) ( Base / Perpendicular ).
- In the “Right Angle Triangle”, in case the perpendicular line is being made from the right angle till the hypotenuse, then in this case, it will result in the total of the three similar triangles.
- In the “Right Angle Triangle”, a circumcircle is being drawn passing via all the 3 vertices – in this case, the ‘Radius of the Same circle will be equivalent to the hypotenuse’s half-length.’
