Classify each angle pair as alternate interior, alternate exterior, or corresponding.

#14) <1 and <3

• alternate interior

• alternate exterior

• corresponding

Classify each angle pair as alternate interior, alternate exterior, or corresponding.

#15) <2 and <7

• alternate interior

• alternate exterior

• corresponding

#16) In the quilt design at the right, line a is parallel to line b. if m<1 = 120 degrees, find m<2 and m<3. Then justify your answer.

Select TWO correct answers and justifications below.

• <2 = 120 degrees because it is alternate exterior to <1, so they are equal

• <3 = 120 degrees because it corresponding to <1, so they are equal

• <2 = 60 degrees because it is supplementary to <1

• <3 = 60 degrees because it is same side exterior with <1, so they are supplementary

#17) Refer to the figure at the right. Line s is parallel to line t. m<2 = 110 degrees and m<11 = 137 degrees. Find m<6 and justify your answer.

• 137 degrees because it corresponds to <11, so they are equal

• 137 degrees because it it vertical to <11, so they are equal

• 70 degrees because it is supplementary to <2

• 110 degrees because it correspond to <2, so they are equal

• 110 degrees because is it supplementary with <8

#18) Refer to the figure at the right. Line s is parallel to line t. m<2 = 110 degrees and m<11 = 137 degrees. Find m<13 and justify your answer.

• 137 degrees because it corresponds to <11, so they are equal

• 137 degrees because it it vertical to <11, so they are equal

• 70 degrees because it is supplementary to <2

• 110 degrees because it corresponds to <2, so they are equal

• 110 degrees because is it vertical to <2 so they are equal

#19) Refer to the figure at the right. Line s is parallel to line t. m<2 = 110 degrees and m<11 = 137 degrees. Find m<4and justify your answer.

• 137 degrees because it corresponds to <11, so they are equal

• 43 degrees because it it same side exterior to <11, so they are supplementary

• 70 degrees because it is supplementary to <2

• 110 degrees because it corresponds to <2, so they are equal

• 110 degrees because is it vertical to <2 so they are equal

#21) Lines m and n are parallel and cut by transversal p. Which of the following pairs of angles represent corresponding angles? Select all that apply.

• <2 and <6

• <4 and < 6

• <3 and <4

• <1 and <5

#22 . Since the given angle was 70 degrees, what must all of the other angles be? Either ______ degrees or ______ degrees ?

• 70

• 180

• 110

• 120

#23) A poster has a triangular image with a base of 4 inches and a height of 8 inches. What is the area of the poster (the triangular image).

• 32 square inches

• 16 square inches

• 12 square inches

• 4 square inches

#24) Classify the angle pair as complementary, supplementary, or neither.

• Complementary

• Supplementary

• Neither
