A

Recall / Warm-Up

Review the basic line and angle facts before naming angle-pair relationships.

1

Angles on a straight line add up to how many degrees?

2

Two lines lie in different planes, point in different directions, and never meet however far extended. What are they called?

B

Fluency Practice

Four boxed diagrams showing parallel, intersecting, perpendicular, and skew line pairs
1

Look at the four labeled line pairs in the figure. Which pair shows perpendicular lines?

2

You construct a line parallel to ABAB at a fixed perpendicular distance of 44 cm using a ruler and set square. What is the perpendicular distance, in cm, between the two lines once drawn?

Two parallel lines cut by a transversal with eight numbered angles; angles 1 and 3 highlighted as vertically opposite
3

In the numbered transversal figure, angles 11 and 33 face each other across the crossing point and share only the vertex. What relationship is this?

4

Two parallel lines are cut by a transversal. One angle measures 75°75\degree. What is the size of its co-interior angle?
