Parallel, Perpendicular and Skew Lines

Front

Define parallel lines.

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart and have the same slope.

Front

What are perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

What are skew lines?

Back

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

Front

If two lines are parallel, what can be said about their slopes?

Back

If two lines are parallel, their slopes are equal.

Front

If two lines are perpendicular, how are their slopes related?

Back

If two lines are perpendicular, the product of their slopes is -1.

Front

Provide an example of parallel lines in a coordinate plane.

Front

What is the relationship between parallel lines and transversals?

Back

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

Front

What is the significance of the distance between parallel lines?

Back

The distance between parallel lines remains constant, which is a key characteristic of parallelism.
