What are Same Side Interior Angles?

Back

Same Side Interior Angles are pairs of angles that lie on the same side of the transversal and between the two lines. They are supplementary, meaning their measures add up to 180 degrees.

What are Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that lie on opposite sides of the transversal and between the two lines. They are congruent when the lines are parallel.

What are Corresponding Angles?

Back

Corresponding Angles are pairs of angles that are in the same position on two different lines cut by a transversal. They are congruent when the lines are parallel.

How do you solve an inequality like 8y < -40?

Back

To solve the inequality, divide both sides by 8. The sign does not flip because you are dividing by a positive number. Thus, y < -5.

What is the sum of (++++) and (---)?

Back

The sum is 1. Each '+' represents +1 and each '-' represents -1. So, 4 + (-3) = 1.

What is the definition of a steep line in a graph?

Back

A steep line in a graph has a larger absolute value of the slope, indicating a greater change in y for a given change in x.

How do you find the missing angle in a triangle?

Back

To find the missing angle in a triangle, subtract the sum of the known angles from 180 degrees.

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

Back

When two parallel lines are cut by a transversal, several pairs of angles are formed that have specific relationships: alternate interior angles are equal, corresponding angles are equal, and same side interior angles are supplementary.
