So think of a degree like an hour, and you’ve got it down: One degree equals 60 minutes. Place the compass point at A, and strike an arc within the angle's rays. Label … size. Step 2:  Place the point of the compass at P and draw an arc that cuts the arm at Q. Mark the left end as point O and the right end as point B. Strike an arc through the angle at a convenient distance. So just like that. This page shows how to construct (draw) a 45 degree angle with compass and straightedge or ruler. If you Taking O as center and any radius, draw an arc cutting OA at B. Let's assume you want to bisect a 60° angle using a compass and straightedge. 2 of 7. another arc of radius PQ near T as shown. We know that the angles in an equilateral triangle are all 60º in arc of radius PQ that cuts the arc drawn in Step 2 at R. We are given a line segment to start, which will become the hypotenuse of a 30-60-90 right triangle. Browse more videos. Show Step-by-step Solutions .
