Bisecting an angle
Bisecting an angle using only a straightedge and a compass is what I will show you here
It is a lot easier than copying angles
I will show you the steps to bisect an acute angle. The steps are still the same when the angle is right or obtuse.
Therefore, study the steps outlined here carefully and you will be able to bisect any angle.
Bisect Angle A:
Place the needle of the compass at vertex A and draw an arc of any size
Call the points where the arc intersects the rays, B and C.
Open the opening of your compass to a distance greater than the distance you used to draw the arc above.
Then, keeping the opening of the compass the same, put the needle of the compass at B and draw and arc
And put the needle of the compass at C and draw and arc
You should get something like that.The two arcs intersect where you see the red spot.
Draw a line between the vertex of A and the red spot and you are done!
