Question

The sides of a triangle are 15cm,36cm,39cm.verify it is a right angled triangle

Answer 1

In a right angled triangle;

p^2+b^2 = h^2 ..Pythagoras theorem

=) 15^2+ 36^2 = 39^2

=) 225 + 1296 = 1521.

Hence it is a right angled triangle.

Hope it's helpful to u.

Answer 2

Heyaa Questioner !!


We are given that -

a = 15

b = 36

c = 39

We can verify it by using Pythagoras theorem ,

${a}^{2} + {b}^{2} = {c}^{2}$
putting a b c 's value

${15}^{2} + {36}^{2} = {39}^{2} \\ \\ = > 225 + 1296 = 1521 \\ \\ = > 1521 = 1521$

Hence we have proved that , third side is greater and the the square of sum of two number is equal to the square of third number

Hence it is. a right angled Triangle

Hope this helps u !!
