C. Color the alternate interior
angles. Color each set a different
color. (You will need two colors)
D. Color the corresponding angles.
Each set should be a different color.
E. Color the pairs of supplementary
angles. Each set should be a
different color. (You will need 8 colors.)
E. Color a pair of complementary
angles.
(You will need four colors)
State Standard 8.2A/B: Identify pairs of angles as complementary, supplementary, adjacent, or vertical
and use these relationships to determine missing angle measures. Determine missing angle measures
using the relationships among the angles formed by parallel lines and transversals.
In questions 1-8, use the picture shown. Lines A and B are parallel.
1. State a pair of angles that have the following relationship:
A. vertical angles ______________________
B. adjacent angles______________________
C. corresponding angles______________________
D. supplementary angles______________________
E. alternate exterior angles______________________
F. congruent angles______________________
G. alternate interior angles______________________
2. Use at least two vocabulary words to describe each angle relationship:
A. ∠1 and ∠2

3. If m∠2 = 138o, then m∠1 = _________ because they are ______________________________________ angles.
4. If m∠2 = 103o, then m∠4 = _________ because they are ______________________________________ angles.
5. If m∠2 = 101o, then m∠8 = _________ because they are ______________________________________ angles.
6. If m∠2 = 127o, then m∠6 = _________ because they are _____________________________________ angles.
7. If m∠2 = 114o, then m∠3 = _________ because they are _____________________________________ angles.
8. If m∠1 = 96o, then m∠7 = _________ because they are _____________________________________ angles.
1n 9-10, the picture shows two parallel pencils crossed with
another pencil. Use this picture to answer the questions.
9. If m∠1 = 75°, then m∠6 = __________.
Explain your reasoning.
10. If m∠2 = 120°, then m∠8 = __________.
Explain your reasoning.
