Angles formed by a Transversal

What are parallel lines?

• Lines that never intersect and are always the same distance apart.

• Lines that intersect at a right angle.

• Lines that meet at a point.

• Lines that are curved and do not follow a straight path.

What is the measure of angle 8 if angle 6 is 75° and they are vertical angles?

• 60°

• 75°

• 90°

• 120°

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

• They are congruent.

• They are supplementary.

• They are complementary.

• They are unequal.

What is a transversal?

• A line that crosses at least two other lines.

• A type of angle formed by two intersecting lines.

• A line that runs parallel to another line.

• A line that connects two points on a curve.

What does it mean for angles to be supplementary?

• Two angles that add up to 90 degrees.

• Two angles that add up to 180 degrees.

• Two angles that are equal in measure.

• Two angles that are adjacent to each other.

If angle B is 45°, what is the measure of angle W if they are vertical angles?

• 30°

• 45°

• 60°

If angle 3 is 75°, what is the measure of angle 6 if lines are parallel?

• 60°

• 75°

• 90°

• 95°

What is the relationship between alternate exterior angles when two lines are parallel?

• They are congruent.

• They are supplementary.

• They are complementary.

• They are equal in measure.

What are corresponding angles?

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

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

• Angles that add up to 90 degrees when two lines intersect.

• Angles that are formed by a transversal cutting through two non-parallel lines.
