IP--Transversals and Angles Pairs

Front

What are parallel lines?

Back

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

Front

What is the value of x when two parallel lines are cut by a transversal and the corresponding angles are equal?

Back

x is the measure of the corresponding angle.

Front

Define linear pair of angles.

Back

A linear pair of angles consists of two adjacent angles that are formed when two lines intersect, and they are supplementary (sum to 180 degrees).

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

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

Back

Same-side interior angles are supplementary when two parallel lines are cut by a transversal.

Front

How do you find the measure of an angle when given the measures of its adjacent angles?

Back

You can find the measure of the angle by subtracting the sum of the adjacent angles from 180 degrees.

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 pairs of angles that are in the same position on two different parallel lines cut by a transversal.

Front

What is the measure of angle C if it is an exterior angle formed by two parallel lines and a transversal?

Back

The measure of angle C can be found using the exterior angle theorem, which states that it is equal to the sum of the two opposite interior angles.

Front

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

Back

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