Question

Determine whether the triangle
whose lengths of sides
sides are
3cm,
4cm, 5cm is a
right angled triangle​

Answer 1

Answer:

We know, every right angle follows Pythagoras theoram

1. length^2+breath^2= hypotenuse^2

LHS=

${3}^{2} + {4}^{2} = 9 + 16 = 25$

RHS =

${5}^{2} = 25$

LHS=RHS

So, this is a right angled triangle.
