What is the Reflexive Property?

Back

The Reflexive Property states that any quantity is equal to itself, i.e., for any segment AB, it holds that AB = AB.

What does the Definition of Midpoint state?

Back

The Definition of Midpoint states that a point M is the midpoint of segment AB if AM = MB.

What is the Vertical Angles Theorem?

Back

The Vertical Angles Theorem states that if two angles are vertical angles (formed by two intersecting lines), then they are congruent.

Front

What is the AAS (Angle-Angle-Side) Congruence Theorem?

Back

The AAS Congruence Theorem states that if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.

Front

What is the Corresponding Angles Theorem?

Back

The Corresponding Angles Theorem states that if two parallel lines are cut by a transversal, then each pair of corresponding angles is congruent.

Front

What is the Linear Pair Postulate?

Back

The Linear Pair Postulate states that if two angles form a linear pair, then they are supplementary, meaning their measures add up to 180 degrees.

What is the significance of 'Given' in geometric proofs?

Back

'Given' refers to the information that is provided in a problem or proof, which is assumed to be true.

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that do not intersect or touch each other at any point, and are equidistant from each other.
