Congruent Angles

Congruent Angles have the same angle (in degrees or radians). That is all.

Congruent Angles
These angles are congruent.

They don't have to point in the same direction.

They don't have to be on similar sized lines.

Just the same angle.

Congruent - why such a funny word that basically means "equal"? Probably because they are only "equal" when laid on top of each other. Anyway it comes from Latin congruere, "to agree". So the angles "agree".
