What is the sum of the interior angles of a triangle?

  • A.90°
  • B.180°
  • C.270°
  • D.360°

Answer: B

The three interior angles of any triangle add to a straight angle.

\[ \angle A + \angle B + \angle C = 180^{\circ} \]

This holds for every triangle, however stretched - it follows from drawing a line through one vertex parallel to the opposite side.
