Front

Fill in the blank: ___________ are located between the lines cut by a transversal.

Back

Interior angles are located between the lines cut by a transversal.

Front

Which segment is skew to D̅E̅?

Back

B̅C̅ is skew to D̅E̅.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

Front

Define skew lines.

Back

Skew lines are lines that do not intersect and are not parallel.

Front

What are interior angles?

Back

Interior angles are angles formed between two lines that are cut by a transversal, located inside the two lines.

Front

What is a transversal?

Back

A transversal is a line that crosses at least two other lines.

Front

What is the relationship between parallel lines and transversals?

Back

When a transversal crosses parallel lines, it creates corresponding angles that are equal.
