What is congruent angle example?

Congruent angles have the same angle measure. For example, a regular pentagon has five sides and five angles, and each angle is 108 degrees. Regardless of the size or scale of a regular polygon, the angles will always be congruent.

What do you mean by congruent angles?

Two angles are congruent if they have the same measure. Two circles are congruent if they have the same diameter.

How do you know if angles are congruent?

If two angles are supplements of the same angle (or congruent angles), then the two angles are congruent. Congruent Complements Theorem: If two angles are complements of the same angle (or congruent angles), then the two angles are congruent.

Are congruent angles always 90 degrees?

Vertical angles are always congruent, which means that they are equal. … Two angles are said to be complementary when the sum of the two angles is 90°. Two angles are said to be supplementary when the sum of the two angles is 180°.

Do congruent angles add up to 180?

Do Congruent Angles Add up to 180? In general, all congruent angles are not supplementary angles. For angles to add up to 180, they must be supplementary angles. So only right angles are congruent as well as supplementary angles because they have the same measure and they add up to 180.
