Directions: Complete all of the problems – show all work and explain answers where necessary.

1) Use the diagram on the right to answer the following questions. Use your notes to find definitions, as needed.

a) Name a pair of complementary angles: _______________________

(Complementary angles are two angles that add to__________.)

b) Name pair of vertical angles: _______________________

(Vertical angles are two angles that are _________________________.)

c) True or false: ∠COB and ∠ AOEare vertical angles. _____________

d) True or false: ∠COD and ∠ AOB are vertical angles. _____________

2) Find the measure of each labeled angle. Give a reason for your solution.The first reason is done for you as an example.

Check this page then continue on! On next side only select one column to work on!

Linear Pairs form supplementary angles

Possible reasons you can use for REASON column (Some more than once):-Linear Pairs form supplementary angles-Vertical angles are congruent

You choose! Choose ONE column to work on! The right column is meant to challenge you!

3) Solve for x. Show all work 3) Two lines intersect at point P two form 4 angles. The m<1 = 2x + 5 and the measure of <3 is x + 10 Solve for <4.

4) Solve for <ECD 4) Solve for <g

5) Solve for x and y: 5) Solve for x and y
