Congruent Triangles ReviewS 1 - Flashcardizz

Front

What are congruent triangles?

Back

Triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

What does SAS stand for in triangle congruence?

Back

Side-Angle-Side; a method to prove triangles are congruent if two sides and the included angle of one triangle are equal to the corresponding parts of another triangle.

Front

What does SSS stand for in triangle congruence?

Back

Side-Side-Side; a method to prove triangles are congruent if all three sides of one triangle are equal to the three sides of another triangle.

Front

What is the Angle-Angle (AA) criterion for triangle similarity?

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

Front

What is the purpose of the Corresponding Parts of Congruent Triangles are Congruent (CPCTC) theorem?

Back

It states that if two triangles are proven to be congruent, then all their corresponding parts (sides and angles) are also congruent.

Front

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

Back

Angle-Side-Angle; if two angles and the included side of one triangle are equal to the corresponding parts of another triangle, the triangles are congruent.

Front

What additional information is needed to prove triangles congruent by SAS?

Back

You need to know the lengths of two sides and the measure of the included angle.

Front

What additional information is needed to prove triangles congruent by SSS?

Back

You need to know the lengths of all three sides of both triangles.

Front

What is the definition of corresponding angles?

Back

Angles that are in the same relative position in two different geometric figures.

Front

What is the definition of corresponding sides?

Back

Sides that are in the same relative position in two different geometric figures.
