How many lines of symmetry does a regular pentagon have?
- 3
- 4
- 5
- 6
Answer: 5. A regular pentagon has 5 equal sides and 5 lines of symmetry — one through each vertex and the midpoint of the opposite side.
GuruMulti-step reasoning.
A regular pentagon. Find each interior angle.
- 108°
- 120°
- 72°
- 90°
Answer: 108°. Sum = (5−2) × 180 = 540. ÷ 5 = 108.
