Answer:

Hello,

Step-by-step explanation:

We know that if a polygon has ‘n’ sides, then it is divided into (n – 2) triangles.  

We also know that, the sum of the angles of a 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

= (2n – 4) right angles
