If line segment wz bisects line segment xy at point z what are two conclusion you can draw from this information?

If a line, in this case XY, is bisected by the line segment, in this case WZ, we are able to form two opposite rays. These rays will now be referred to as XZ and YZ because the line segment bisected the line at point Z.

One of the two conclusions is that which is already written above. Another is that, we form two angles. These angles can be named as, WZX and WZY. These angles are supplementary. This means that their measures would add up to 180°. This is also in consideration that they share one common side and the other side of each of the angles are opposite rays.
