Question

which of the following angles can be drawn using set squares.

• A. ${30}^{\circ }$
• B. ${45}^{\circ }$
• C. ${60}^{\circ }$
• D. ${90}^{\circ }$

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A

${30}^{\circ }$

B

${45}^{\circ }$

C

${60}^{\circ }$

D

${90}^{\circ }$

The angles of one of the set square are ${45}^{\circ },{90}^{\circ },{45}^{\circ }$.

The angles of the other set square are ${30}^{\circ },{90}^{\circ },{60}^{\circ }$.

So, ${30}^{\circ },{45}^{\circ },{60}^{\circ },{90}^{\circ }$ can be drawn directly.
