Dec 12 Core 2 Geometry Intro to Congruency Flashcardizz

Front

What is congruency in geometry?

Back

Congruency in geometry means that two figures have the same shape and size. This can be shown through congruence statements.

Front

What is a congruence statement?

Back

A congruence statement is a mathematical statement that indicates two geometric figures are congruent, often written in the form of triangles, such as @@ riangle ABC eq riangle XYZ @@.

Front

How do you denote congruent segments?

Back

Congruent segments are denoted with the symbol '≅'. For example, if segment AB is congruent to segment CD, it is written as AB ≅ CD.

Front

What does it mean for angles to be congruent?

Back

Two angles are congruent if they have the same measure. This can be indicated by the symbol '≅'.

Front

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

Back

The AA criterion states that if two angles of one triangle are congruent to two angles of another triangle, the triangles are similar.

Front

What is the Side-Side-Side (SSS) criterion for triangle congruence?

Back

The SSS criterion states that if three sides of one triangle are congruent to three sides of another triangle, the triangles are congruent.

Front

What is the Side-Angle-Side (SAS) criterion for triangle congruence?

Back

The SAS criterion states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, the triangles are congruent.

Front

What is the purpose of a congruence statement?

Back

A congruence statement is used to show that two geometric figures are identical in shape and size, allowing for the application of various geometric properties.

Front

How do you identify corresponding angles in congruent triangles?

Back

Corresponding angles in congruent triangles are angles that are in the same relative position in each triangle.

Front

What is the relationship between corresponding sides in congruent triangles?

Back

In congruent triangles, corresponding sides are equal in length.
