Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet or intersect, no matter how far they are extended.

Front

What is the relationship between intersecting lines?

Back

Intersecting lines are lines that cross each other at one point.

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

Front

How can you identify parallel lines in a diagram?

Back

Front

What is the symbol for a ray?

Back

Front

What does it mean for lines to be skew?

Back

Skew lines are lines that do not intersect and are not parallel, often found in different planes.

Front

What is the sum of angles around a point?

Back

The sum of angles around a point is always 360 degrees.

Front

What is a transversal line?

Back

A transversal line is a line that crosses two or more other lines, creating angles.
