LO:  SWBAT will apply and use deductive reasoning, postulates and properties to prove mathematical statements.
-----------------------------------------------------------------------------------------------------------

We will mostly work on the handout which we will add to your notebook.

 Here are two examples:

Now it's your turn.  Try to fill in the blanks in these two proofs.
If  you do not finish in class, this becomes homework.

8. Conditional Statements

For September 9th class

8.  CONDITIONAL STATEMENTS
---------------------------------------------------------------------------------------------------------------------
LO:  SWBAT will determine the validity of a conditional statement, its converse, inverse
and contrapositive.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
(Textbook Chapter 2-3, starting from page 91)


1. Conditional Statements
To change a statement to an If-Then statement is to make a conditional statement.  

Let's look at the statement:  "Rain means it's cloudy."
Changing this to a conditional means identifying the hypothesis and conclusion then adding the if-then words to it like this:
 

The "if" is always followed by the hypothesis and the "then" is always followed by the conclusion.

Now you try.  Rewrite these advertisements into If-Then forms:

2.  Converse, Inverse, and Contrapositive
Other statements based on the conditional statements are Converse, Inverse and Contrapositive.  They are formed by exchanging and negating the hypothesis and conclusion of the conditional statements in various ways.

Notice that the symbols for the Conditional Statement reads as "p to q".

Now you try: using the same conditionals from the advertisements from section 1 above, write each one's converse, inverse and contrapositive.

3.  Counterexample
A Counterexample is a true example to prove a statement false.

For example:
Statement:  "If it has four right angles, then it's a square"
This is a false statement.  We then give the counterexample:  A rectangle.

The counterexample proves that the statement was false.

Now you try:  for each false statement from #2 above, provide a counterexample.

4.  Biconditional Statements

A conjunction of two statements where both the conditional and its converse are true is called biconditional.

7. Logical Reasoning

7. LOGICAL REASONING
--------------------------------------------------------------------------------------------------------
LO:  SWBAT use logical reasoning to prove statements are true and find counterexamples to disprove statements that are false.
 -----------------------------------------------------------------------------------------------------------------------------
Before we start, let's look at the format we will be using:

• Lower case letters will be used to name a statement.

 1. NEGATION

Negation is changing the truth value of a statement to its opposite value.  We designate the negated value with the symbol "~".

Example Statement:

p:  Austin is the capital city of Texas.    The truth value of this statement is True.  

~p:  Austin is NOT the capital city of Texas.  The truth value is now False.

Again, the ~p statement is the negated statement.

2. CONJUNCTION

A conjunction is a compound statement formed by joining two or more statements with the word and.  We then use the statements to write a compound statement.  (Compound just means mixing two things together in one). 

p:  Parallel lines have the same slopes

q:  Vertical angles are congruent

r:  The expression -5x + 11x simplifies to -6x

To write the compound statement, we use the symbol ∧.

So now we write our compound statements:

• p∧q (read as "p and q"):  Parallel lines have the same slope and vertical angles are congruent.
• ~p ∧ ~q (read as "not p and not q"):  Parallel lines DOES NOT have the same slope and vertical lines are NOT congruent.
• ~q ∧ r (read as "not q and r"):  Vertical angles are NOT congruent and the expression -5x + 11x simplifies to -6x.

3. DISJUNCTION

A disjunction is a compound statement formed by joining two or more statements with the word or.  We then use the the statements to write a compound statement.

Let's use the same statements from above

p:  Parallel lines have the same slopes

q:  Vertical angles are congruent

r:  The expression -5x + 11x simplifies to -6x

To write the compound statement, we use the symbol ∧.

So now we write our compound statements:

So now we write our compound statements:

• p∧q (read as "p and q"):  Parallel lines have the same slope or vertical angles are congruent.
• ~p ∧ ~q (read as "not p and not q"):  Parallel lines DOES NOT have the same slope or vertical lines are NOT congruent.
• ~q ∧ r (read as "not q and r"):  Vertical angles are NOT congruent or the expression -5x + 11x simplifies to -6x.

Note that the statements are identical except they are now joined by the word "OR" instead of "AND".

4.  TRUTH TABLES

We will fill in this table in class and discuss it.

5.  VENN Diagrams

We will examine the Venn Diagram and interpret data from it.
