Front

What are Vertical Angles?

Back

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

Front

What does it mean for two lines to be Perpendicular?

Back

Two lines are perpendicular if they intersect to form right angles (90 degrees).

What symbol represents Perpendicular lines?

Front

What is the Reflexive Property?

Back

The Reflexive Property states that any geometric figure is congruent to itself. For example, segment AB is congruent to segment AB.

Front

What is the Angle-Side-Angle (ASA) Congruence Postulate?

Back

The ASA Postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the definition of Congruent Triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

What is the definition of Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines. They are congruent when the lines are parallel.

Front

What is the definition of a Bisector?

Back

A bisector is a line, ray, or segment that divides an angle or a segment into two equal parts.

Front

What is the definition of a Midpoint?

Back

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

Front

What is the definition of Corresponding Angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal. They are congruent.
