Question

67.5° angle can be constructed by bisecting the angles

• A.
  30° and 90°
• B.
  60° and 90°
• C.
  45° and 90°
• D.
  45° and 60°

Answer 1

The correct option is C

45° and 90°
67.5° = 45° + 22.5°
$={45}^{\circ }+\frac{{90}^{\circ }-{45}^{\circ }}{2}$
Thus, the angle 67.5º can be constructed by bisecting the angles 45° and 90°.
Hence, the correct answer is option (c).
