IP--Transversals and Angles Pairs

Front

What is a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles whose non-common sides form a straight line. They are supplementary, meaning their measures add up to 180 degrees.

Front

What are supplementary angles?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What is the measure of angles formed by parallel lines cut by a transversal?

Back

When two parallel lines are cut by a transversal, several pairs of angles are formed, including corresponding angles, alternate interior angles, and alternate exterior angles, all of which are equal.

Front

How do you find the value of x in angle problems?

Back

To find the value of x in angle problems, set up equations based on the relationships between the angles (e.g., supplementary, complementary, or equal) and solve for x.

Front

What is the relationship between alternate interior angles when lines are parallel?

Back

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

Front

What is the relationship between same-side interior angles when lines are parallel?

Back

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

Front

If angle 1 measures 27 degrees, what is the measure of angle 4 if the lines are parallel?

Back

Angle 4 also measures 27 degrees because corresponding angles are equal when lines are parallel.

Front

What is a transversal in geometry?

Back

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

Front

What are vertical angles?

Back

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