Step-by-step explanation:

Answer

(i) Hexagon

Numbers of sides, and = 6

Sum of the interior angles = (2n-4)90°

= ((2 x 6)-4) x 90°

=(124)90°

= 8 x 90°

= 720°

Sum of the exterior angles = 360°.

(ii) Octagon

Numbers of sides, n = 8

Sum of the interior angles = (2n-4)90°

= ((2 x 8)-4) x 90°

= (1644)90°

= 12 x 90°

= 1080°

Sum of the exterior angles = 360°.
