Question

Which of the following angles can be made only using a protractor?

• A. True
• B. False
• C. 50${}^{\circ }$
• D. 60${}^{\circ }$

Answer 1

Answer: (B), (C)

The correct options are
B

False

C 50${}^{\circ }$

A 60${}^{\circ }$ angle can be drawn by drawing a line segment, cutting an arc centred at one end of the segment. Then make a second arc centred at the point where the previous arc intersects the line segment, cutting the previous arc at a point. Then joining the end point of the segment and the point of intersection of two arcs will give 60${}^{\circ }$ angle.
Hence, D is correct.
Also by bisecting 60${}^{\circ }$ angle, we can make 30${}^{\circ }$ angle.
Hence, A is also correct.
The remaining two angle can be made only by using a protractor.
