Angles formed by Transversals

Front

What are angles formed by transversals?

Back

Angles formed when a transversal intersects two or more lines, creating various angle relationships.

Front

Define Corresponding Angles.

Back

Angles that are in the same position on different parallel lines cut by a transversal.

Front

What are Alternate Interior Angles?

Back

Angles that lie between two lines and on opposite sides of a transversal.

Front

Define Alternate Exterior Angles.

Back

Angles that lie outside two lines and on opposite sides of a transversal.

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What is a Linear Pair of Angles?

Back

A pair of adjacent angles that are supplementary, meaning they add up to 180 degrees.

Front

If Angle 1 = 27°, what is the measure of Angle 4 if they are Vertical Angles?

Back

27° (Vertical Angles are equal).

Front

If Angle 1 = 27°, what is the measure of Angle 5 if they are Corresponding Angles?

Back

27° (Corresponding Angles are equal).

Front

If Angle 5 = 63°, what is the measure of Angle 6 if they are Linear Pair?

Back

117° (Linear Pair angles add up to 180°).

Front

What is the relationship between Alternate Interior Angles?

Back

They are equal when the lines are parallel.
