What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

• They are equal.

• They are supplementary.

• They are complementary.

• They are unequal.

What is a transversal?

• A line that intersects two or more lines at different points.

• A line that runs parallel to another line.

• A line that is perpendicular to a given line.

• A line that connects two points on a curve.

What are corresponding angles?

• Angles that are in the same position on two different lines cut by a transversal; they are equal.

• Angles that are supplementary and add up to 90 degrees.

• Angles that are opposite each other when two lines cross; they are equal.

• Angles that are adjacent and share a common vertex.

What are supplementary angles?

• Angles that add up to 90°.

• Angles that add up to 180°.

• Angles that are equal in measure.

• Angles that add up to 360°.

What are vertical angles?

• Angles that are adjacent to each other when two lines intersect; they are equal.

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

• Angles that are supplementary when two lines intersect; they are equal.
