Final answer:
Congruent angles have the same measure and are important in geometry to understand the relationships between lines and angles in geometric figures.
Step-by-step explanation:
Angles that have the same value are called congruent angles. Congruent angles have the same measure, meaning they have the same number of degrees. For example, two angles that both measure 60 degrees are congruent angles.
This concept is important in geometry and can be used to solve problems involving angles and shapes. By knowing that angles are congruent, we can make conclusions about the relationships between lines and angles in geometric figures.
