What does AAS stand for in triangle congruence?

Back

Angle-Angle-Side: A method to prove triangles are congruent by showing two angles and a non-included side are equal.

Front

What does SSS stand for in triangle congruence?

Back

Side-Side-Side: A method to prove triangles are congruent by showing all three sides are equal.

Front

What is the HL theorem in triangle congruence?

Back

Front

How can you determine if two triangles are congruent using the ASA method?

Back

If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, they are congruent.

Front

What is the significance of the SSA condition in triangle congruence?

Back

SSA does not guarantee triangle congruence; it can lead to ambiguous cases.

Front

If two triangles have two sides and the included angle equal, what can be concluded?

Back

The triangles are congruent by the SAS criterion.

Front

What is the first step in proving triangles are congruent?

Back

Identify the congruence criteria that apply based on the given information.

Front

Can two triangles be congruent if only one angle is known?

Back

No, at least two angles or one angle and the included side must be known.
