Given:

Line segment WZ bisects line segment XYLine segment XY bisects line segment WZTo prove:

Triangles WAX and ZAY are congruent

Statement:

1. Segment WZ bisects XYReasons:

1. given

2. Segments XA and AY are

congruent

2. when a segment is bisected the resulting segments are

congruent

3. Segment XY bisects WZ 3. given
