Construct an Angle Bisector

You can use a compass and a straightedge

to bisect an angle.

To construct the bisector of 
XYZ:

Step 1 Step 2 Step 3

Put the compass point Open the compass to With the same compass

on Y. Construct an arc measure the length of opening and the compass

that intersects both rays arc AB. With the same point on B, construct an

of the angle. Label the compass opening and arc that intersects the

points of intersection the compass point on other arc. Label the point

Aand B. A, construct an arc of intersection P.

inside the angle. Draw YP.

YP is the bisector of 
XYZ.
