Proving theorems about segments and angles — Homework
Write or complete each two-column proof, citing definitions, postulates, and properties of equality or congruence.
- 1.What property justifies the statement "angle Q ~= angle Q"?
- 2.Given angle 1 ~= angle 2, what property justifies angle 2 ~= angle 1?
- 3.Given angle 1 and angle 2 are vertical angles, and angle 1 = 82 degrees, find angle 2 and state the theorem used.
- 4.N is the midpoint of segment JK. What is the reason for the statement "JN ~= NK"?
- 5.Write a two-column proof: Given that angle 1 and angle 2 form a linear pair, and angle 3 and angle 2 also form a linear pair, prove angle 1 ~= angle 3.
