Question

Using two set-square of the geometry box, an angle of ${15}^{\circ }$ can be drawn.

• A. True
• B. False

Answer 1

The correct option is A True

First draw a ${45}^{\circ }$ angle (∠ABC) using one of the set-squares. Place the other set-square alligned with the base and draw a ${30}^{\circ }$ angle (∠ABD). Thus resulting an angle (∠DBC) of ${15}^{\circ }$.

${45}^{\circ }$ - ${30}^{\circ }$ = ${15}^{\circ }$
