Congruent Triangle Proofs

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a criterion for proving triangles congruent where two angles and a non-included side are known.

What is the ASA criterion for triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for proving triangles congruent where two angles and the included side are known.

What are Vertical Angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent.

Front

What is the definition of Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal. They are congruent.

Front

What is the significance of the Congruence Symbol (≅)?

Back

The congruence symbol (≅) indicates that two geometric figures are congruent, meaning they have the same shape and size.

Front

What is the purpose of a proof in geometry?

Back

A proof in geometry is a logical argument that establishes the truth of a statement or theorem based on previously established statements.

Front

What does it mean for triangles to be congruent?

Back

Triangles are congruent if they have the same size and shape, which can be proven using criteria like AAS, ASA, or SAS.
