What does it mean for two planes to be parallel?

Back

Two planes are parallel if they do not intersect and are always the same distance apart.

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines on opposite sides of a transversal.

What is a transversal in geometry?

Back

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

Front

How do you identify parallel lines in a diagram?

Back

Parallel lines are typically indicated by arrows on the lines or by observing that they never meet.

What is the significance of angle relationships in solving for unknown variables?

Back

Angle relationships help establish equations that can be solved to find unknown angle measures or variables.

Front

How can you determine if two angles are corresponding?

Back

Two angles are corresponding if they occupy the same relative position at each intersection of the transversal with the parallel lines.
