Congruent Triangles Review

Front

What are Alternate Interior Angles?

Back

Alternate Interior Angles are angles that lie between two parallel lines and on opposite sides of a transversal. They are congruent when the lines are parallel.

Front

What is the SSS Postulate?

Back

The SSS (Side-Side-Side) Postulate states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent.

Front

What is the ASA Postulate?

Back

The ASA (Angle-Side-Angle) Postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the AAS Postulate?

Back

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

Front

What are Vertical Angles?

Back

Vertical Angles are the angles opposite each other when two lines intersect. They are always congruent.

Front

What does it mean for triangles to be congruent?

Back

Triangles are congruent if they have the same size and shape, which means all corresponding sides and angles are equal.

Front

What is the definition of corresponding angles?

Back

Corresponding Angles are angles that are in the same position on two parallel lines in relation to a transversal. They are congruent when the lines are parallel.

Front

What is the definition of an angle bisector?

Back

An angle bisector is a line or ray that divides an angle into two equal parts.

Front

If ∆EHG≅∆KFC, what can we say about the corresponding sides?

Back

If ∆EHG≅∆KFC, then EH≅FC, HG≅KF, and EG≅KC.

Front

What is the relationship between corresponding angles in congruent triangles?

Back

All corresponding angles in congruent triangles are congruent.
