Exploring Angles Formed by Parallel Lines and Transversals

What are the four types of angle pairs discussed in the previous lesson?

• Interior, Exterior, Adjacent, Vertical

• Acute, Obtuse, Right, Straight

• Vertical, Adjacent, Complementary, Supplementary

• Corresponding, Same Side Interior, Alternate Interior, Alternate Exterior

When two lines are parallel, what can be said about corresponding angles?

• They are vertical

• They are supplementary

• They are complementary

• They are congruent

Which of the following angle pairs are congruent when lines are parallel?

• Supplementary Angles

• Same Side Interior Angles

• Alternate Interior Angles

• Adjacent Angles

What is the measure of angle ABC if it is corresponding to an angle measuring 80 degrees?

• 60 degrees

• 80 degrees

• 100 degrees

• 180 degrees

If angle DEF is given by the equation 2x - 45 and it corresponds to an angle given by x + 30, what is the value of x?

• 30

• 75

• 45

• 105

What is the measure of angle EDF if it is an alternate exterior angle to an angle measuring 125 degrees?

• 90 degrees

• 55 degrees

• 125 degrees

• 180 degrees

If angle TUS is a same side interior angle to an angle measuring 65 degrees, what is the measure of angle TUS?

• 115 degrees

• 65 degrees

• 180 degrees

• 90 degrees

What should you do if you know one angle when you have parallel lines?

• You can only find the adjacent angle

• You can find the vertical angle only

• You cannot find any other angles

• You can find the other seven angles

What is the key difference between theorems and converses discussed in the next lesson preview?

• Theorems are always true, converses are not

• Theorems start with parallel lines, converses start with angle pairs

• Theorems are easier to understand than converses

• Theorems are about angles, converses are about lines

What should you do if you have questions about the material covered?

• Ask a friend

• Write them down and ask in class

• Search online

• Ignore them
