Angle Proofs 2 Column

Front

What is the definition of an angle proof?

Back

An angle proof is a logical argument that demonstrates the truth of a statement about angles using definitions, postulates, and previously proven theorems.

What are the two columns in a two-column proof?

Back

The two columns in a two-column proof consist of statements on one side and corresponding reasons on the other side.

Front

What is the purpose of using reasons in a two-column proof?

Back

Reasons provide justification for each statement made in the proof, ensuring that the argument is valid and based on established principles.

Front

What is the Vertical Angles Theorem?

Back

The Vertical Angles Theorem states that if two angles are opposite each other when two lines intersect, then those angles are congruent.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the definition of adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

What is the definition of a linear pair?

Back

A linear pair is a pair of adjacent angles formed when two lines intersect, and their non-common sides form a straight line.

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.
