Question: If two lines are parallel and a transversal creates an angle of 40°, what is the measure of the alternate exterior angle?

Options:

Correct Answer: 40°

Solution:

The alternate exterior angle is equal to the angle formed by the transversal, so it is 40°.

If two lines are parallel and a transversal creates an angle of 40°, what is the measure of the alternate exterior angle?

If two lines are parallel and a transversal creates an angle of 40°, what is the measure of the alternate exterior angle?

Step 1: Understand that parallel lines are lines that never meet and are always the same distance apart.
Step 2: Identify the transversal, which is a line that crosses the two parallel lines.
Step 3: Recognize that when the transversal crosses the parallel lines, it creates angles.
Step 4: Note that alternate exterior angles are the angles that are on opposite sides of the transversal and outside the parallel lines.
Step 5: Remember that alternate exterior angles are equal when two lines are parallel.
Step 6: Since the angle created by the transversal is 40°, the alternate exterior angle is also 40°.

Alternate Exterior Angles – When two parallel lines are cut by a transversal, the alternate exterior angles are equal.
Transversal Angles – A transversal creates various angles with the lines it intersects, and certain angles are congruent or supplementary based on their positions.
