All you need to do is split the given lines into two equal pieces.

This can be used a solid review and class practice exercise. When a ray or line breaks an angle into two equal angles it is called a bisector. If a ray bisects an angle of a triangle, then it divides the opposite side of the triangle into segments that are proportional to the other two sides. /SM 0.02
