Angle Relationships and Finding Missing Angles

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal. They are equal in measure.

Front

What are Alternate Interior Angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are Alternate Exterior Angles?

Back

Angles that are on opposite sides of the transversal and outside the two parallel lines. They are equal in measure.

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect. They are equal in measure.

Front

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

Back

When a transversal crosses parallel lines, several pairs of angles are formed, including corresponding, alternate interior, alternate exterior, and vertical angles, which have specific relationships.

Front

How do you determine if two angles are supplementary?

Back

Two angles are supplementary if the sum of their measures equals 180 degrees.

Front

How do you determine if two angles are complementary?

Back

Two angles are complementary if the sum of their measures equals 90 degrees.

Front

What is the equation setup for finding x if two angles are supplementary?

Back

Set up the equation as: angle1 + angle2 = 180.

Front

What is the equation setup for finding x if two angles are complementary?

Back

Set up the equation as: angle1 + angle2 = 90.

Front

If two angles are equal, how do you set up the equation to solve for x?

Back

Set up the equation as: angle1 = angle2.
