# If the followings

Given: Three sides of a triangle are 8 cm, 15 cm and 17 cm.

To check if the triangle is a right-angled triangle, we verify by Pythagoras theorem.

Taking the longest side to be hypotenuse and other two sides as base and perpendicular, we have,

Hypotenuse, h = 17 cm

Perpendicular, p = 8 cm

Base, b = 15 cm

According to Pythagoras theorem,

h2 = p2 + b2

172 = 82 + 152

289 = 64 + 225

289 = 289

Hence, verified that the triangle is a right- angled triangle.
