2.2 Opener Transversal Angle Relationships

Front

What is a Vertical Angle?

Back

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

Front

What is a Corresponding Angle?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others. They are equal.

Front

What is a Linear Pair?

Back

A linear pair consists of two adjacent angles that are formed when two lines intersect. The sum of the angles in a linear pair is always 180 degrees.

Front

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal. They are equal when the lines are parallel.

Front

What are Consecutive Interior Angles?

Back

Consecutive interior angles are pairs of angles that lie between two lines on the same side of a transversal. They are supplementary when the lines are parallel.

Front

What are Alternate Exterior Angles?

Back

Alternate exterior angles are pairs of angles that lie outside two lines and on opposite sides of a transversal. They are equal when the lines are parallel.

Front

What is the relationship between Vertical Angles?

Back

Vertical angles are always equal to each other.

Front

How do you identify Corresponding Angles?

Back

Corresponding angles can be identified as angles that occupy the same relative position at each intersection of the transversal with the two lines.

Front

What is the sum of angles in a Linear Pair?

Back

The sum of angles in a linear pair is always 180 degrees.

Front

What happens to Alternate Interior Angles when lines are parallel?

Back

When the lines are parallel, alternate interior angles are equal.
