Intro to Geometry Proofs

Front

What does the Segment Addition Postulate state?

Back

If point X is between points R and T on a line, then RX + XT = RT.

Front

What is the Reflexive Property in geometry?

Back

The Reflexive Property states that any geometric figure is congruent to itself.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, which is a criterion for triangle congruence.

Front

What is the definition of an angle bisector?

Back

An angle bisector is a ray that divides an angle into two congruent angles.

Front

What does it mean for two angles to be complementary?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

What is the definition of a midpoint?

Back

A midpoint is a point that divides a segment into two equal parts.

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What is the purpose of a proof in geometry?

Back

A proof is a logical argument that demonstrates the truth of a geometric statement.

Front

What is the difference between a theorem and a postulate?

Back

A theorem is a statement that has been proven based on previously established statements, while a postulate is a statement accepted without proof.

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.
