Parallel Lines cut by a Transversal

If angle 1 = 27°, what is the measure of angle 4 if they are corresponding angles?

• 25°

• 27°

• 30°

• 45°

Define alternate interior angles.

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

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

• Angles that are adjacent to each other and on the same line.

• Angles that are formed by two intersecting lines and are equal.

What is the sum of the measures of angles around a point?

• 180°

• 360°

• 90°

• 270°

What is a transversal?

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

• 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.

Identify the relationship: Angle 2 and Angle 4.

• Consecutive Interior Angles

• Alternate Interior Angles

• Corresponding Angles

• Exterior Angles

What are parallel lines?

• Lines that intersect at a right angle.

• Lines in a plane that never meet and are always the same distance apart.

• Lines that converge at a point.

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

What are corresponding angles?

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

• Angles that are equal in measure but not necessarily in position.

• Angles that are supplementary to each other.

• Angles that are formed when two parallel lines are cut by a transversal.

What is the relationship between angle 2 and angle 8 if they are alternate exterior angles?

• Angle 2 is greater than Angle 8.

• Angle 2 and Angle 8 are equal.

• Angle 2 is less than Angle 8.

• Angle 2 and Angle 8 are complementary.
