Lengths of sides of a triangle are 3 cm, 4 cm and 5 cm. The triangle is

Given: Lengths of sides of a triangle are 3 cm, 4 cm and 5 cm

Formula Used/Theory:-

Pythagoras theorem:-

Base² + Height² = Hypotenuse²

As Lengths of sides of a triangle are 3 cm, 4 cm and 5 cm

Squaring all sides

9,16,25

⇒ 9 + 16 = 25

Which is equal to square of 3^rd side

∴ Pythagoras theorem get proved

Hence;

It is a right angled triangle
