Question

Which of the following cannot be constructed using a ruler and a compass?

• A. 35°
• B. 45°
• C. 90°
• D. 180°

Answer 1

The correct option is A

35°

Angles which are multiples of ${15}^{\circ }$ can be constructed using compass and ruler.
${30}^{\circ },{45}^{\circ },{60}^{\circ },{90}^{\circ },{120}^{\circ }$ are some angles which can be drawn with the help of a ruler and compass.
${35}^{\circ }$ angle cannot be constructed using a ruler and compass since it is not a multiple of ${15}^{\circ }$.
