Question

Find the measure of each interior angle of a regular pentagon and regular hexagon(using formula) .

Answer 1

No. of sides in a regular Pentagon =5

Sum of exterior angle =360°

each exterior angle =360°/no of sides

=360/5

=72°

THEREFORE each interior angle =180°-72°

=108°

No of sides in a regular hexagon=6

Sum of exterior angle=360°

each exterior angle=360°/6

=60°

therefore each interior angle =180°-60°

=120°

Answer 2

Answer:

Regular hexagons interior angle sum using the formula (n-2) × 180 = (6-2)×180 = 4 × 180° = 720°

every interior angle then would be 720/6 = 120°

Now exterior angles are always 360°

so all angles = 360/6 = 60°
