Question

Using which of the following, it is not possible to construct a ${60}^{\circ }$ angle?

• A. Protractor, Ruler
• B. Compass, Ruler
• C. Set Square (30º-60º-90º)
• D. Set Square (45º-45º-90º)

Answer 1

The correct option is D

Set Square (45º-45º-90º)

We can't draw a ${60}^{\circ }$ angle using a set square that has ${45}^{\circ }$-${45}^{\circ }$-${90}^{\circ }$ angles. Using a protractor and compass, and by using a Set Square (${30}^{\circ }$-${60}^{\circ }$-${90}^{\circ }$), we can draw ${60}^{\circ }$ angle.
