What are same side angles?

Back

Same side angles are pairs of angles that are on the same side of a transversal and between two parallel lines.

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never intersect and are always the same distance apart.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines in relation to a transversal.

Front

What is a transversal?

Back

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

Front

Identify a pair of same side angles in a diagram with parallel lines and a transversal.

Back

Example: Angles 1 and 7 are same side angles.

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are equal when two parallel lines are cut by a transversal.

Front

What is the relationship between alternate exterior angles?

Back

Alternate exterior angles are equal when two parallel lines are cut by a transversal.

Front

How do you identify corresponding angles in a diagram?

Back

Corresponding angles are found in matching corners when a transversal crosses parallel lines.

Front

What is the sum of the angles on a straight line?

Back

The sum of the angles on a straight line is 180 degrees.
