Geometry - 5.1=5.3 Flashcard Review 2

Front

What is the definition of congruence in geometry?

Back

Two figures are congruent if they have the same shape and size.

Front

What can be concluded if two angles are right angles?

Back

If two angles are right angles, they are congruent.

Front

How do you find the measure of an angle when given a variable?

Back

Substitute the value of the variable into the equation to find the angle's measure.

Front

What is the Segment Congruence Theorem?

Back

If two segments are congruent, then they have the same length.

Front

What is the relationship between parallel lines and angles?

Back

When two lines are parallel, certain angles formed by a transversal are congruent.

Front

What does it mean for triangles to be congruent?

Back

Triangles are congruent if their corresponding sides and angles are equal.

Front

What is the significance of right angles in geometric proofs?

Back

Right angles are often used to establish congruence and relationships between shapes.

Front

How can you determine if two triangles are congruent using side lengths?

Back

Use the Side-Side-Side (SSS) or Side-Angle-Side (SAS) congruence postulates.

Front

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

Back

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

Front

What is the purpose of geometric proofs?

Back

Geometric proofs are used to demonstrate the validity of geometric statements and theorems.
