How can we make an angle of 130' using ruler and compass?
The angle measuring 130º cannot be constructed using a ruler and compass. It can be constructed using a protractor.
The angles measuring 30º, 45º, 60º, 75º, 90º, 120º, 135º, 150º, 180º and their bisectors can be constructed using the compass. The bisectors of the angles so formed can also be constructed using the compass.
