Exploring Parallel Lines and Angles

What is a transversal?

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

• A line that never intersects another line

• A line that is perpendicular to another line

• A line that is parallel to another line

Which of the following is true about parallel lines?

• They never intersect

• They are always perpendicular

• They intersect at one point

• They intersect at multiple points

What are corresponding angles?

• Angles on the same side of the transversal in the same position

• Angles on opposite sides of the transversal inside the parallel lines

• Angles that share the same vertex

• Angles on opposite sides of the transversal outside the parallel lines

If one corresponding angle is 125 degrees, what is the measure of the other corresponding angle?

• 125 degrees

• 55 degrees

• 75 degrees

• 100 degrees

What are alternate interior angles?

• Angles on the same side of the transversal in the same position

• Angles on opposite sides of the transversal inside the parallel lines

• Angles on opposite sides of the transversal outside the parallel lines

• Angles that share the same vertex

If one alternate interior angle is 55 degrees, what is the measure of the other alternate interior angle?

• 75 degrees

• 100 degrees

• 125 degrees

• 55 degrees

What are alternate exterior angles?

• Angles on opposite sides of the transversal inside the parallel lines

• Angles on the same side of the transversal in the same position

• Angles that share the same vertex

• Angles on opposite sides of the transversal outside the parallel lines

If one alternate exterior angle is 100 degrees, what is the measure of the other alternate exterior angle?

• 75 degrees

• 55 degrees

• 125 degrees

• 100 degrees

What are vertical angles?

• Angles on the same side of the transversal in the same position

• Angles on opposite sides of the transversal inside the parallel lines

• Angles that share the same vertex and are opposite each other

• Angles on opposite sides of the transversal outside the parallel lines

If one vertical angle is 100 degrees, what is the measure of the other vertical angle?

• 125 degrees

• 75 degrees

• 100 degrees

• 55 degrees
