Hello there!

Pentagon = 5 sides.

For regular pentagon: 360/5 = 72. 180 - 72 = 108 degrees at each interior.

I hope this helps.

Interior Angle Sum Theorem: 180° (n - 2)  ; where n is the number of sides

a Pentagon has 5 sides, so n = 5

Sum = 180°(5 - 2)

       = 180°(3)

       = 540°

Sum divided by the number of sides equals the measure of each angle.

Each Angle = 540° ÷ 5  

                   = 108°

Answer: 108°
