Properties of Parallel Lines

Front

What is a transversal in relation to parallel lines?

Back

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

Front

What are the properties of same side interior angles when a transversal crosses parallel lines?

Back

Same side interior angles are supplementary, meaning they add up to 180 degrees.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal; they are equal in measure.

Front

What is the relationship between corresponding angles when a transversal intersects parallel lines?

Back

Corresponding angles are equal when a transversal intersects parallel lines.

Front

What is the value of y if the equation formed by parallel lines and a transversal is y + 10 = 39?

Back

y = 29.

Front

What is the definition of parallel lines?

Back

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

Front

What is the sum of the interior angles on the same side of a transversal?

Back

The sum of the interior angles on the same side of a transversal is 180 degrees.

Front

What is the relationship between exterior angles formed by a transversal and parallel lines?

Back

Exterior angles that are on opposite sides of the transversal are equal.

Front

How can you identify alternate exterior angles?

Back

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

Front

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

Back

Understanding angle relationships helps in setting up equations to solve for unknown angles when parallel lines and transversals are involved.
