3. Truth value of Conditionals

Determine the truth value of the following conditional statements. If it is false, then find a counterexample:

1. If $a \leq 3$, then $a > 3$
2. If two lines intersect, then it must create a right angle
3. If $a=1$, $b=2$, $c=3$, then $a+b+c>5$
4. If a polygon has 3 sides, then it is a triangle.
4. Determine the truth value of the statement below for each set of conditions:

###### Topic Notes
Notes:

A conditional statement is a statement written in the form "if, then".
The phrase after the word "if" is called a hypothesis.
The phrase after the word "then" is called the conclusion.
In symbolic form the conditional statement is written as:

$p \to q$

Where $p$ is the hypothesis, $q$ is the conclusion, and $\to$ implies it is an "if, then" statement.
