उत्तर
Two angles are said to be congruent, if they have equal measures.
Explanation:
In geometry, congruent angles are angles that have the same measure, regardless of their orientation or the lengths of their arms.
-
For example, if one angle measures 45° and another also measures 45°, then they are congruent angles.
-
They may look different in size if drawn with longer or shorter lines, but as long as their angle measures are the same, they are congruent.
