Exploring Angles Formed by Parallel Lines and Transversals

The video tutorial explains the concept of parallel lines cut by a transversal, using real-world examples like roadways. It covers essential math vocabulary related to angles, such as supplementary, vertical, and corresponding angles. The tutorial includes examples and practice problems to help students understand how to identify and solve for angles formed by transversals. It also demonstrates solving angle equations using number bonds and provides interactive practice for identifying angles.

What is the term for a line that intersects two or more lines?

• Diagonal

• Perpendicular line

• Transversal

• Parallel line

What is the sum of two supplementary angles?

• 360 degrees

• 90 degrees

• 120 degrees

• 180 degrees

Which type of angle is less than 90 degrees?

• Straight angle

• Obtuse angle

• Right angle

• Acute angle

What are vertical angles?

• Angles that are supplementary

• Angles that are opposite each other and congruent

• Angles that are on the same side of the transversal

• Angles that are adjacent to each other

What is the measure of a straight angle?

• 360 degrees

• 45 degrees

• 90 degrees

• 180 degrees

What are corresponding angles?

• Angles that are in the same relative position when a transversal cuts through two or more lines

• Angles that are on the same side of the transversal and inside the parallel lines

• Angles that are on the outside of the parallel lines and on opposite sides of the transversal

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

If angle A is an obtuse angle, which of the following is also an obtuse angle?

• Angle D

• Angle B

• Angle C

• Angle E

What is the corresponding angle to a 109-degree angle in a transversal?

• 90 degrees

• 180 degrees

• 109 degrees

• 71 degrees

How do you find the unknown angle in a pair of supplementary angles if one angle is 109 degrees?

• Divide 109 degrees by 2

• Multiply 109 degrees by 2

• Subtract 109 degrees from 180 degrees

• Add 109 degrees to 180 degrees

If angle 2 is 40 degrees, what is the measure of angle 6?

• 100 degrees

• 80 degrees

• 140 degrees

• 40 degrees
