Question

The lengths of the sides of some triangles are given below. Find out which of them are right-angled triangles.

(6) 1.5 cm, 1.6 cm, 1.7 cm

Answer 1

The lengths of the sides of a triangle are 1.5 cm, 1.6 cm and 1.7 cm
Longest side = 1.7 cm
Square of longest side = (1.7)² = 2.89
Side one = 1.5 cm
Square of side one = (1.5)² = 2.25
Side two = 1.6 cm
Square of side two = (1.6)² = 2.56
Sum of Square of side one and square of side two = 2.25 + 2.56 = 4.81
Square of longest side
Hence, this is not a right-angled triangle.
