Parallel lines cut by a transversal

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.

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

If two angles are vertical angles, what can be said about their measures?

• They are equal.

• They are supplementary.

• They are complementary.

• They are adjacent.

What are same side interior angles?

• Angles that are on the same side of the transversal and inside the two lines; they are supplementary.

• Angles that are on opposite sides of the transversal and inside the two lines; they are complementary.

• Angles that are on the same side of the transversal and outside the two lines; they are supplementary.

• Angles that are on opposite sides of the transversal and outside the two lines; they are supplementary.

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 connects two points on a curve.

• A line that is perpendicular to another line.

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 180 degrees.

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

• Angles that are adjacent and share a common vertex.

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

• They are complementary.

• They are equal.

• They are supplementary.

• They are congruent.

What are same side exterior angles?

• Angles that are on the same side of the transversal and outside the two lines; they are supplementary.

• Angles that are on opposite sides of the transversal and outside the two lines; they are complementary.

• Angles that are on the same side of the transversal and between the two lines; they are supplementary.

• Angles that are on opposite sides of the transversal and between the two lines; they are supplementary.

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

• They are equal.

• They are supplementary.

• They are complementary.

• They are unequal.

What are alternate interior angles?

• Angles that are on the same side of the transversal and outside the two lines; they are equal.

• Angles that are on opposite sides of the transversal and inside the two lines; they are equal.

• Angles that are on the same side of the transversal and inside the two lines; they are supplementary.

• Angles that are on opposite sides of the transversal and outside the two lines; they are complementary.

What are alternate exterior angles?

• Angles that are on the same side of the transversal and inside the two lines; they are equal.

• Angles that are on opposite sides of the transversal and outside the two lines; they are equal.

• Angles that are on the same side of the transversal and outside the two lines; they are supplementary.

• Angles that are on opposite sides of the transversal and inside the two lines; they are complementary.
