How do you indicate congruent segments in a diagram?
Answered by Reiny
by placing identical markings on each side, often a single stroke for one set of equal sides, a double stroked bar for the second set etc.

Here is a diagram showing such markings.
Also notice how they mark equal angles, re your other posting.
