Geometry Semester 1 Review

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a postulate that states if two angles and the non-included side of one triangle are congruent to two angles and the non-included side of another triangle, then the triangles are congruent.

Front

What does AAA indicate in triangle congruence?

Back

AAA stands for Angle-Angle-Angle, which indicates that if all three angles of one triangle are congruent to all three angles of another triangle, the triangles are similar but not necessarily congruent.

Front

What is the Reflexive Property?

Back

The Reflexive Property states that any geometric figure is congruent to itself. For example, if triangle ABC is considered, then triangle ABC ≅ triangle ABC.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a postulate that states if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a postulate that states 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 Subtraction Property in geometry?

Back

The Subtraction Property states that if two quantities are equal, then subtracting the same amount from both sides will keep them equal.

Front

What is the Definition of a Bisector?

Back

A bisector is a line, ray, or segment that divides an angle or a segment into two equal parts.

Front

What is the SSS postulate?

Back

SSS stands for Side-Side-Side, a postulate that states if all three sides of one triangle are congruent to all three sides of another triangle, then the triangles are congruent.

Front

What are Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that are on opposite sides of a transversal and inside two parallel lines. If the lines are parallel, these angles are congruent.

Front

How do you determine if two triangles are congruent using AAS?

Back

To determine if two triangles are congruent using AAS, check if two angles and the non-included side of one triangle are congruent to the corresponding two angles and the non-included side of the other triangle.
