- 900
- 640
- 540
- 720
Show answer and solution
Correct answer: D. 720
A simple n-gon has an angle sum of (n - 2) x 180, so for 6 sides it is 4 x 180 = 720 degrees.

Worked practice questions
Which polygon has interior angles summing to 1440 degrees?
- dodecagon
- nonagon
- decagon
- octagon
Show answer and solution
Correct answer: C. decagon
Setting (n - 2) x 180 = 1440 gives n - 2 = 8, so n = 10, which is a decagon.
A simple polygon has 9 sides. What is its interior angle sum in degrees?
- 1620
- 1260
- 1080
- 1440
Show answer and solution
Correct answer: B. 1260
With n = 9 the formula (n - 2) x 180 gives 7 x 180 = 1260 degrees.
