4 Row 1, Col 1 The part of a conditional that follows the word “If” What is the Hypothesis?

5 1,2 is an example of this Property What is the Reflexive Property of Equality?

6 1,3 this is the missing reason What is Given?

7 1,4 is an example of this... What is the definition of complementary angles?

8 2,1 p: it is a tree q: it has roots are the hypothesis and conclusion for this conditional What is “If it is a tree then it has roots”?

9 2,2 is an example of this Property What is the Addition Property of Equality?

10 2,3 is the missing statement What is ZX = XY + ZY?

11 2,4 FG + GH = FH is an example of this… What is the Segment Addition Postulate? FGHFGH

12 3,1 p: it is a tree q: it has roots are the hypothesis and conclusion for this converse. What is “If it has roots, then it is a tree”?

13 3,2 is an example of this Property What is the Subtraction Property of Equality?

14 3,3 this is the missing statement. What is 4s – 9 = 2s + 17

15 3,4  5 and  6 form a linear pair and is an example of this… What is definition of linear pairs? 5 6

16 4,1 p: it is a triangle q: it has 3 closed sides are the hypothesis and conclusion for this biconditional What is “It is a triangle if and only if it has 3 closed sides”?

17 4,2 is an example of this Property What is the Substitution Property of Equality?

18 4,3 is the missing statement and reason What is LN ≅ MO and Definition of Congruent Segments? NO

19 4,4 What is the definition congruent angles? is an example of this…

20 5,1 It is a square if and only if it has 4 sides is a false biconditional because of this reason. What is because the converse is false?

21 5,2 is an example of using these two Properties. What are the Multiplication Property of Equality and Subtraction Property of Equality?

22 5,3 is the missing statement and reason What are AF = BF and Subtraction Property of Equality?

23 5,4 is an example of this… What is the Overlapping Angle Theorem? P Q S T U 1 2
