Triangle angle sum?

  • 180°
  • 360°
  • 90°
  • 270°

Answer: 180°. Triangle interior angles sum to 180°.

ProCompare and infer.

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.
