A pentagon has five sides with equal lengths
The sum of interior angles of a pentagon is 540°
To get the measure of an interior angle you perform division
In this case divide the total sum of interior angles by the number of sides
This will be : 540° / 5 = 108°
The measure of an interior angle of a hexagon is : 108 °
The measure of the exterior angle will be ; 180° - 108° = 72°
Answer : Interior angle measure ; 108°
Exterior angle measure ; 72°
