Question 1152603
<font color=black size=3>
With the given info that DE = OM, and that EG = PM, we can draw this out.

The segments with the single tickmark are the same length.
The segments with the double tickmarks are the same length.


The angles E and M are between the segments mentioned above. So this is the missing piece of info if we wanted to use SAS.


If angle E = angle M, then we can use SAS to prove the triangles congruent.
More technically, if we knew that angle DEG = angle OMP, then we can use SAS to prove the triangles congruent.


Here is an updated drawing

If we know the green angles are the same measure, then we can use SAS to prove the triangles congruent.
