Q2 of 23 Page 1

Solve any four sub-questions:

Sides of a triangle are 7, 24 and 25. Determine whether the triangle is right-angled triangle or not.

By Pythagoras if sum of squares of two sides is equal to square of largest side then triangle is said to be right angled

Here given sides of triangle are 7, 24 and 25


Largest side = 25


252 = 625


Sum of squares of remaining two sides


72 + 242 = 49 + 576


= 625


∴ 72 + 242 = 252


Therefore triangle having sides 7,24 and 25 is a right angled triangle
