please follow me and mark me as branlist....

thankyou

Step-by-step explanation:

If a polygon has

′

n

′

sides, then it is divided into (n−2) triangles.

We know that the sum of the angles of triangle = 180

∘

.

Therefore, the sum of the angles of (n−2) triangles = 180 × (n−2)

⇒ 2×right angles×(n−2)

⇒2(n−2) right angles
