Unit 2 Study Guide
In the first section you will be asked to demonstrate knowledge of the skills seen on your
quiz and the review stations. The second section of the test will consist of proofs.
-- Any theorems, postulates, definitions, and properties that appear in Chapter Two and any
material that we worked on in Chapter One are fair game for the test.
--I would recommend making flash cards for any vocabulary or rules with which you are still
having trouble.
--A majority of the proofs on the test will have some of the statements and/or reasons filled
in already. You will need to fill in the blanks. There will be one proof that you must complete
in its entirety (but it will be a small proof).
-- Another part of the test will be an incorrect proof. You will have to identify what is wrong
with the proof and why the steps are wrong. Then, you will have to show the correct way to
complete the given proof.
Definitions:
Congruent Segments; Midpoint of a Segment; Bisector of a Segment; Congruent Angles; Bisector of an
Angle; Complementary Angles; Supplementary Angles; Vertical Angles; Linear Pair;
Perpendicular Lines.
NOTE: You will NEVER use “Definition of Vertical Angles” as a reason in a proof. You may use
“Vertical Angles are Congruent” or “Vertical Angle Theorem.”
Postulates: Segment Addition Postulate, Angle Addition Postulate
Theorems:
Midpoint Theorem; Angle Bisector Theorem; Vertical Angle Theorem;
Properties:
Equality: Addition; Subtraction; Multiplication; Division; Substitution; Reflexive; Symmetric;
Transitive
Congruence: Reflexive; Symmetric; Transitive
Also be familiar with:
Conditional Statements, Hypothesis, Conclusion, Converse, Biconditional, Counterexamples
