Question

Check whether 3 cm, 4 cm and 5 cm are the sides of right angles triangle or not.​

Answer 1

answer.

Using Pythagoras theorem

H^2=B^2+P^2

H=longest side 5 cm

5^2=3^2+4^2

25=9+16

25=25cm

longest side is equal to sum of other side,so this show it is right angle triangle

make me brainlist

Answer 2

Step-by-step explanation:

We know that hypotenuse is a largest side.

So, hypotenuse = 5 cm

Checking pythagoras theorem

(Hypotenuse*2) = (Base*2) + (Perpendicular*2)

5*2 = 3*2 + 4*2

25 = 9 + 16

25 = 25

:- Pythagoras theorem is satisfied

Hence, 3 cm, 4 cm, 5 cm forms side of a right angled triangle.
