Question

Qhat is the measure of each interior angle of a regular hexagon

Answer 1

Sum of all interior and “exterior angles” = 360n where n is the number of sides.

sum of exterior angles is 360.

So, the sum of interior angles = 360(n-1)·(1–1/(n-1))/2

Answer 2

120°

the sum of the interior angles of a polygon = 180°( n - 2)

where n is the number of sides

here n = 6 ⇒ sum = 180° × 4 = 720°

thus each interior angle = $\frac{720}{6}$ = 120°
