Question

The sides of a triangle are 15cm, 8cmand17cm, Is this triangle, a right angled triangle​

Answer 1

➠ Given :

Sides of a triangle:

a = 15 cm.

b = 8 cm.

c = 17 cm.

➠ To Find :

if a triangle is right-angled triangle.

➠ Solution :-

we know, that in a right angle triangle:

(Hypotenuse)² = (Base)²+(Height)²

⟹ (17)² = (8)² + (15)²

⟹ 289 = 64 + 225

⟹ 289 = 289

Hence, the triangle is a right angle triangle.
