If they have the same degrees than they're congruent. There are many possibilites. It depends where the angle is placed. Let say that you don't know the measurement of the angle and there are two parrallel lines with another line crossing (transversal). Rules/ Theorems state that consecutive interior/exterior, alternative interior/exterior are all congruent. Vertical angles are also congruent. Etc.. You just need to know the properties of the shape or know the prob. If i don't know the situation, i can't point you to which theorem you should use.

No, not all angles in a trapezoid are congruent. A trapezoid may have two pairs of congruent angles, or may have no congruent angles.
What two angles have the same measure what is it called?
The two angles are congruent. They are congruentangles. Congruent is basically 'same' in math. We often say congruent shapes, congruent, angles, and congruent sides.
How are two angles triangles be congruent?
If they have identical sides and angles then they are congruent
