15. Write the if-then form, the converse, the inverse and the contrapositive of the following
statement. Then circle whether the statement is true or false.
Vertical angles are congruent
If-then: _____________________________________________________________ True False
Converse: ___________________________________________________________True False
Inverse: _____________________________________________________________True False
Contrapositive: ______________________________________________________ True False
16. Write the converse of the following statement. If both statements are true, rewrite them as a
bi-conditional statement.
If a ray is a bisects an angle, then the ray cuts the angle into two congruent angles.
Converse: _______________________________________________________________T or F
Biconditional:_________________________________________________________________
17. Use the Venn Diagram above to help you determine whether the following statements are
true or false. Provide a counterexample for questions you believe to be false. Explain those you
claim to be true.
a) If a quadrilateral is a rectangle, it is a parallelogram.
b) All squares are rhombuses.
c) All trapezoids are parallelograms.

18. Use the law of syllogism to write a valid conclusion
If you have a cell phone, then you text your friends. If you text your friends, then you will go to
the party.
Conclusion: _________________________________________________________________
19. What can you conclude from the following two statements?
If an angle measures less than 90 , then it is acute.
mB  63
Conclusion: _________________________________________________________________
20. Use the following statement: If you are at the skate park, then you are a skateboarder.
Label the Venn Diagram based on your conditional statement.
Using the diagram, write one conclusion, if any, that can be drawn
from the following statements:
a) Bob is at the skate park.___________________________
b) Juanita is not a skateboarder.__________________________
c) Sally is not at the skate park. ________________________
d) Billy is a skateboarder._________________________
21. If p represents “the sun is shining”, and q represents “people will dine outside”, write the following
in words:

a)
b)
p  q _____________________________________________________________________
c) Write in symbolic notation: If people dine outside, then the sun is not shining.
22. Let p represent “a figure has point symmetry” and let l represent “a figure has line
symmetry”. Translate the following into symbols.
a) A figure has both point and line symmetry
_____________
b) A figure as point or line symmetry.
