Geometry Congruence Flashcard

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are congruent.

Front

What are remote interior angles in relation to an exterior angle?

Back

Remote interior angles are the two interior angles that are not adjacent to the exterior angle.

Front

How do you denote congruence between two angles?

Back

Congruence between two angles is denoted using the symbol '≅'.

Front

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

Back

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

Front

What is the definition of corresponding sides in congruent triangles?

Back

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

Front

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

Back

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

Front

What is the purpose of a congruence statement in geometry?

Back

A congruence statement indicates which parts of two geometric figures are congruent.

Front

What is the definition of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect, and they are always congruent.

Front

How can you find the measure of an angle if you know the measures of the other angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees; you can find the unknown angle by subtracting the sum of the known angles from 180.
