SSS and SAS

Front

What does SSS stand for?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence.

Front

What does SAS stand for?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence.

Front

What is the SSS Congruence Postulate?

Back

If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the SAS Congruence Postulate?

Back

If two sides and the included angle of one triangle are equal to two sides and the included angle 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 cross. They are always congruent.

Front

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal. They are congruent.

Front

What is the Reflexive Property?

Back

The Reflexive Property states that any geometric figure is congruent to itself.

Front

What is the Transitive Property?

Back

The Transitive Property states that if one figure is congruent to a second figure, and the second figure is congruent to a third figure, then the first and third figures are congruent.

Front

How can you prove triangles are congruent?

Back

You can prove triangles are congruent using SSS, SAS, ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), or HL (Hypotenuse-Leg for right triangles).

Front

What is an Angle Bisector?

Back

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