Match the definition or description with the correct word.

5=x andy+4=x , then5=y+4 — A. Law of Contrapositive  An educated guess — B. Inductive Reasoning

6(2a+1)=12a+12 — C. Inverse 
2,4,8,16,32,… — D. Transitive Property of Equality 
AB¯¯¯¯¯¯¯¯≅CD¯¯¯¯¯¯¯¯ andCD¯¯¯¯¯¯¯¯≅AB¯¯¯¯¯¯¯¯ — E. Counterexample 
∼p→∼q — F. Conjecture  Conclusions drawn from facts. — G. Deductive Reasoning
 If I study, I will get an “
A ” on the test. I did not get anA . Therefore, I didn’t study. — H. Distributive Property 
∠A and∠B are right angles, therefore∠A≅∠B . — I. Symmetric Property of Congruence  2 disproves the statement: “All prime numbers are odd.” — J. Right Angle Theorem
K. Definition of Right Angles
