Exploring Parallel Lines and Transversals

Mrs. Bradfield reviews angle types, including supplementary, complementary, and vertical angles. She introduces parallel lines cut by a transversal, explaining the formation of eight angles and their relationships, such as vertical and corresponding angles. The video includes problem-solving examples to find unknown angles using these relationships. The session concludes with a summary of key concepts.

What is the sum of supplementary angles?

• 180 degrees

• 360 degrees

• 90 degrees

• 45 degrees

If one angle is 105 degrees, what is its supplementary angle?

• 75 degrees

• 85 degrees

• 95 degrees

• 105 degrees

What is the sum of complementary angles?

• 90 degrees

• 45 degrees

• 180 degrees

• 360 degrees

What are vertical angles?

• Angles that add up to 180 degrees

• Angles that add up to 90 degrees

• Angles that are opposite each other when two lines cross

• Angles that are adjacent to each other

What is a transversal?

• A line that never touches another line

• A line that cuts across two parallel lines

• A line that is perpendicular to another line

• A line that is parallel to another line

How many angles are formed when a transversal cuts across two parallel lines?

• 4

• 10

• 6

• 8

What is the relationship between vertical angles in parallel lines cut by a transversal?

• They are always different

• They are always equal

• They add up to 180 degrees

• They add up to 90 degrees

If angle 1 is 110 degrees, what is angle 2 in a supplementary pair?

• 70 degrees

• 80 degrees

• 90 degrees

• 100 degrees

What are corresponding angles?

• Angles that are in the same position at different intersections

• Angles that add up to 180 degrees

• Angles that add up to 90 degrees

• Angles that are adjacent to each other

If angle 1 is 63 degrees, what is angle 5 in a corresponding pair?

• 90 degrees

• 117 degrees

• 180 degrees

• 63 degrees
