Question

The sum of all the angles of a triangle is ___ degrees.

Answer 1

Factual: Sum of the angles of the triangle is ${180}^{\circ }$.

We have learned that for any polygon, sum of its interior angles is = $(n-2)\times {180}^{\circ }$ [where n is the number of sides]

For a triangle, n = 3

So, sum of all interior angles = $(3-2)\times {180}^{\circ }={180}^{\circ }$
