Question

Is the triangle with sides 25 cm, 5 cm and 24 cm a right triangle? Give reasons for your answer.

Answer 1

Let us assume that,

A = 25 cm

B = 5 cm

C = 24 cm

Now, Using Pythagoras Theorem,

We have,

A² = B² + C²

B² + C² = (5)² + (24)²

B² + C² = 25 + 576

B² + C² = 601

A² = 600

600 ≠ 601

A² ≠ B² + C²

Since the sides does not satisfy the property of Pythagoras theorem, triangle with sides 25 cm, 5 cm and 24 cm is not a right triangle.
