Day 2-Congruent Triangles Shortcuts CW

Front

What does SSS stand for in triangle congruence?

Back

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

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 equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is the definition of congruent triangles?

Back

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

Front

What is the Angle-Angle-Angle (AAA) criterion?

Back

AAA states that if two triangles have equal corresponding angles, they are similar, but not necessarily congruent.

Front

How can you determine if two triangles are congruent using the SSS postulate?

Back

Measure the lengths of all three sides of both triangles. If all three pairs of corresponding sides are equal, the triangles are congruent.

Front

How can you determine if two triangles are congruent using the SAS postulate?

Back

Measure two sides and the included angle of both triangles. If the two sides and the included angle of one triangle are equal to the corresponding parts of the other triangle, they are congruent.

Front

What is the definition of corresponding angles in triangles?

Back

Corresponding angles are angles that are in the same relative position in two different triangles.

Front

What is the definition of corresponding sides in triangles?

Back

Corresponding sides are sides that are in the same relative position in two different triangles.

Front

What is the purpose of using triangle congruence postulates?

Back

Triangle congruence postulates are used to prove that two triangles are congruent, which helps in solving geometric problems and establishing relationships between figures.

Front

What is the definition of the included angle in a triangle?

Back

The included angle is the angle formed between two sides of a triangle.
