Construct an angle
In order to construct a 75o angle with compass without making 90o angle construct a 45o angle by taking a line segment PQ. P will be the angle's vertex.
Draw the perpendicular bisector RS of line segment PQ.
The angle ∠QPR has a measure of 45°
At PR draw an angle of 30o by bisecting a 60 degree angle
