2.1 PLC Formative - Parallel Lines

Front

What are alternate angles?

Back

Angles that are on opposite sides of a transversal and inside the two lines it intersects.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always congruent.

Front

What are linear pair angles?

Back

Two adjacent angles that form a straight line; they are supplementary.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate interior angles?

Back

They are congruent.

Front

If two parallel lines are cut by a transversal, what can be said about the same-side interior angles?

Back

They are supplementary.

Front

What is the sum of the angles in a linear pair?

Back

180 degrees.

Front

What is the relationship between alternate exterior angles when two parallel lines are cut by a transversal?

Back

They are congruent.

Front

Define transversal in the context of parallel lines.

Back

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