Question

can we construct an angle of 52.5?

Answer 1

To construct an angle of 52.5° firstly construct an angle of 90°, then construct an angle of 120° and then plot an angle bisector of 120° and 90° to get an angle 105° (90° + 15°). Now, bisect this angle to get an angle of 52.5°.

Answer 2

yes, with the help of D but not by compass as it dont divide by 15.
