Parallel Lines Cut By a Transversal FLASHCARD

Front

What are 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 is a transversal?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position at each intersection where a transversal crosses two lines.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles on opposite sides of the transversal but inside the two lines.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles on opposite sides of the transversal but outside the two lines.

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

When two parallel lines are cut by a transversal, corresponding angles are equal.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

When two parallel lines are cut by a transversal, alternate interior angles are equal.

Front

What is the relationship between alternate exterior angles when two parallel lines are cut by a transversal?

Back

When two parallel lines are cut by a transversal, alternate exterior angles are equal.

Front

If ∠D = 64°, what is the measure of the corresponding angle?

Back

The measure of the corresponding angle is also 64°.

Front

What is the equation to find the value of x when given angles?

Back

The equation is formed by setting the sum of the angles equal to 180° or using the properties of angles formed by a transversal.
