Angles Study Guide

Front

What is an alternate interior angle?

Back

An alternate interior angle is formed when a transversal crosses two parallel lines, creating pairs of angles on opposite sides of the transversal but inside the two lines.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate interior angles?

Back

The alternate interior angles are equal.

Front

What is the measure of angle b if it is 36°?

Back

Angle b measures 36°.

Front

How do you find the measure of an angle when given its alternate interior angle?

Back

The measure of the angle is equal to its alternate interior angle if the lines are parallel.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180°.

Front

What is the measure of angle 1 if it is given as 44°?

Back

Angle 1 measures 44°.

Front

What are corresponding angles?

Back

Corresponding angles are formed when a transversal crosses two lines, and they are in the same position relative to the lines.

Front

If two lines are parallel, what can be said about corresponding angles?

Back

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

Front

What is the definition of a transversal?

Back

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

Front

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

Back

Interior angles on the same side of a transversal are supplementary, meaning they add up to 180°.
