Question

Do sides 7 cm, 24 cm and 5 cm form a right angled triangle? Give reason​

Answer 1

Step-by-step explanation:

${24}^{2} = {7}^{2} + {5}^{2} \\ 576 = 49 + 25 \\ 576 = 74 \\ they \: are \: not \: equal \: so \: it \: is \: not \: a \: right \: angled \: triangle$

Answer 2

Answer:

No, But if instead of 5cm if the the side is 25cm then it forms a right angled triangle.

Explanation:

A triangle is said to to be right angled only if it obeys Pythagoras Theorem

=> $(Hypotenuse)^2$ = Sum of the squares of the sides
