Connect each endpoint of AB to opposite endpoints of CD. As there are two ways of doing this, the general case will be that each way (A to C and B to D vs A to D and B to C) will produce different congruent pairs. Sometimes one of the ways will not produce one.

Construct the perpendicular bisector of the two previously constructed segments. Point O will be where the two perpendicular bisectors meet.


Note
1.The lines shown ae DE and BC. I thought I had labeled them correctly but they got mislabeled.
2. the circle centered on C was placed in order to construct BC as being the same length as DE.
