Video: Understanding Parallel Lines and Angles

What is essential to have when determining angle relationships?

• A calculator

• A ruler

• Parallel lines and a transversal

• A protractor

What is the role of a transversal in parallel lines?

• It measures the distance between lines

• It intersects the parallel lines

• It makes the lines parallel

• It divides the angles equally

What is the relationship between the measures of corresponding angles when two lines are parallel?

• Adjacent

• Supplementary

• Complementary

• Equal

What must be true for corresponding angles to be equal?

• The lines must intersect

• Any two lines will work

• The lines must be parallel

• The lines must be perpendicular

How do you solve for x when given corresponding angles?

• Set the angles equal and solve

• Divide the angles

• Subtract the angles

• Multiply the angles

What type of angles add up to 180 degrees?

• Vertical angles

• Alternate interior angles

• Consecutive interior angles

• Corresponding angles

How do you find the value of x with consecutive interior angles?

• Add the angles and set equal to 180

• Divide the angles by 2

• Subtract the angles from 180

• Multiply the angles

What mistake did the teacher make in the last equation?

• Forgot to add the angles

• Incorrectly divided by 2

• Used the wrong theorem

• There was no mistake
