3.1-3.3 Review

Front

What are skew lines?

Back

Skew lines are lines that do not intersect and are not parallel. They exist in different planes.

Front

What does it mean for a line to be perpendicular to a plane?

Back

A line is perpendicular to a plane if it intersects the plane at a right angle (90 degrees).

Front

How can you determine if two lines are parallel?

Back

Two lines are parallel if they are in the same plane and do not intersect.

Front

What is the Converse of Corresponding Angles Postulate?

Back

If two lines are cut by a transversal and the corresponding angles are equal, then the lines are parallel.

Front

Identify the relationship: Line BE is perpendicular to plane DEF. What does this imply?

Back

It implies that Line BE intersects Plane DEF at a right angle.

Front

What is the definition of a plane in geometry?

Back

A plane is a flat, two-dimensional surface that extends infinitely in all directions.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two lines and on opposite sides of the transversal.

Front

What is the significance of the Converse of Alternate Exterior Angles Theorem?

Back

If two lines are cut by a transversal and the alternate exterior angles are equal, then the lines are parallel.

Front

How do you identify parallel planes?

Back

Parallel planes are planes that do not intersect and are always the same distance apart.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different lines cut by a transversal.
