To indicate that angles are congruent, matching angle marks such as arcs or hash marks are typically used. For angles formed by lines AB and CD, you would place the same number of arcs or hash marks in each angle that you want to show as congruent. For example, if angles ∠1 and ∠2 are congruent, you might place one arc in both angles to signify their equality.
if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
Yes. The lower base angles are congruent. The upper base angles are congruent.
Angle Angle Side is a method one can use to prove that two triangles are congruent. Basically, if any two pairs of angles and the side between these angles are congruent, then the triangles are congruent as well.
Congruent angles are angles that have the same measure. For example, if angle A measures 30 degrees and angle B also measures 30 degrees, then angles A and B are congruent. Additionally, angles that are vertically opposite when two lines intersect are also congruent. In general, any angles that are equal in measurement are considered congruent.

Congruent angles (or equivalent angles) have the same angle measure.
Two angles that are congruent have the same angle measurement.
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
angle bisectorangles bisector is the line that divides an angle into two congruent angles.
Yes. The lower base angles are congruent. The upper base angles are congruent.
A line that bisects an angle into two different congruent angles is called an angle bisector.

No. An angle can have only one angle!
