Parallel Lines cut by a Transversal Review

Front

What are Vertical Angles?

Back

A pair of opposite congruent angles formed by intersecting lines.

Front

If two sides of a triangle are congruent, what can be said about the angles opposite those sides?

Back

The angles opposite those sides are congruent.

Front

What are Supplementary Angles?

Back

Two angles whose sum is 180 degrees.

Front

What type of angle pair are ∠1 and ∠5 if they are in the same position relative to two parallel lines cut by a transversal?

Back

Corresponding angles.

Front

What are Alternate Exterior Angles?

Back

Angles that lie outside a pair of lines (exterior) and on opposite sides of a transversal; they are congruent when the lines are parallel.

Front

Define Transversal.

Back

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

Front

What are Adjacent Angles?

Back

Two angles that share a common side and a common vertex but do not overlap.

Front

What is the relationship between Corresponding Angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are congruent.

Front

What are Same Side Interior Angles?

Back

Angles that lie on the same side of the transversal and between the two lines; they are supplementary when the lines are parallel.

Front

What is the definition of Perpendicular Lines?

Back

Two lines that intersect to form right angles (90 degrees).
