Overlapping Triangles

Front

What is an overlapping triangle?

Back

An overlapping triangle occurs when two triangles share a common part, such as a side or angle.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

Front

What does it mean for angles to be congruent?

Back

Congruent angles are angles that have the same measure.

Front

What is the AAS congruence criterion?

Back

AAS (Angle-Angle-Side) states that if two angles and the non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, the triangles are congruent.

Front

What is the SAS congruence criterion?

Back

SAS (Side-Angle-Side) states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie on opposite sides of a transversal and inside the two lines.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie on opposite sides of a transversal and outside the two lines.

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that lie on the same side of the transversal and inside the two lines.

If angles 4 and 8 are corresponding, what can we say about their measures?

Back

Angles 4 and 8 are congruent.
