Question

The sides of a triangle are 15 cm, 36 cm and 39 cm. Verify that it is a right angled triangle.
​

Answer 1

Step-by-step explanation:

to check whether it's a right angle triangle Pythagoras theorem should be true

as 39cm is the longest side we know

that it is the hypotenuse

(39)²= (15)²+(36)²

1521 = 225 + 1296

since LHS and RHS are equal we can say that the mentioned triangle is right angled

Answer 2

${\huge{\star{ \huge{ \fbox { \purple{answer}}}}}}}}$

Given sides are 15,36,39

So if 15²+36²=39² then it is a right angled triangle..

15²+36²=225+1296=1521

39²=1521

HERE hypotenuse²=side²+side²

so it is a right angled triangle.
