#### 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

#### Solution

We have,

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

∴ a^{2} = 49, b^{2} = 576 and c^{2} = 625

Since, a^{2} + b^{2} = 49 + 576

= 625

= c^{2}

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

Is there an error in this question or solution?
