What is the sum of all interior angles of a convex hexagon (a 6-sided polygon)?
Answer and explanation
Correct answer: C. 720 degrees
- Step 1: Interior angle sum formula: S = (n - 2) 180 degrees. Step 2. For a hexagon with n = 6: S = (6 - 2) 180 = 4 180 = 720 degrees. Answer: 720 degrees. Why not the others:* 540 degrees is for a pentagon (n=5); 900 degrees is for a heptagon (n=7); 1,080 degrees is for an octagon (n=8).
