Question

plas answer this question . its urgent.

Answer 1

If any of them is right angled triangle,,then square of Length of biggest side should equal to the sum of square of other 2 sides,

Checking :-

$25^2$ should equal to ($7^2 + 24^2$)

$625 should equal to 49 + 576$

625 is equal to 625

then, it is a right angled triangle

2)-

$10^2$ should equal to ($5^2 + 8^2$)


100 should  equal to 25+64


100 $\neq$ 89

then, it is not a right angled triangle 



i hope this will help you
