Question

The sides of triangle is given below. Determine it is right triangle or not.

a = 7 cm, b = 24 cm and c = 25 cm

Answer 1

We have,

a = 7 cm, b = 24 cm and c = 25 cm

∴ a² = 49, b² = 576 and c² = 625

Since, a² + b² = 49 + 576

= 625

= c²

Then, by converse of Pythagoras theorem, given triangle is a right triangle.
