Congruent sides or segments have the exact same length. Equal should be used to relate the lengths or measurements of two sides angles or parts of shapes. Maybe because they are only equal when placed on top of each other. Anyway it comes from latin congruere to agree so the shapes agree.

The following is a list of mathematical symbols used in all branches of mathematics to express a formula or to represent a constant. In geometry two figures or objects are congruent if they have the same shape and size or if one has the same shape and size as the mirror image of the other. Very loosely you can think of it as meaning equal but it has a very precise meaning that you should understand completely especially for complex shapes such as polygons.
