Answer» 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

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
