Check whether the following measures (in cm) can be the sides of a right-angled triangle or not.

1.5, 3.6, 3.9

Given: length of sides are 1.5,3.6,3.9

Formula Used/Theory:-

⇒ Pythagoras theorem:-

Base² + Height² = Hypotenuse²

Largest side is 3.9cm

Other 2 sides are 1.5cm,3.6cm

As hypotenuse is largest side

Hypotenuse² = (3.9)² = 15.21

Sum of square of other 2 sides of triangle

(3.6)² + (1.5)² = 12.96 + 2.25

= 15.21

LHS = RHS

Hence Pythagoras theorem verified

∴ it is a right angled triangle

Result:- Triangle having sides of these lengths is right

angled triangle
