Question

Use the figure to identify each pair of angles as complementary angles, supplementary angles, vertical angles, or none of these.

A: angles 1 and 5
B: angles 3 and 5
C: angles 3 and 4

Answer 1

Complimentary means parts of a 90* angle. So 1 and 5. Then 3 and 5 are vertical, and 3&4 supplementary because they make up a 180*. So comp=90, supp=180, and vertical are opposite sides of an X shape
