Triangle angle sum?
- 180°
- 360°
- 90°
- 270°

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 teacher marks 'triangle angles 70°, 40°, 70°' wrong. Why?
- Pupil is CORRECT — sum is 180°.
- Should be 90°.
- Should be 120°.
- Should be 60°.
Answer: Pupil is CORRECT — sum is 180°.. 70 + 40 + 70 = 180.
