3.5 - Conditional Statements and Their Converse
This section has many definitions so the video starts with these - please be prepared to write them down.
A conditional statement is just a statement that can be written as: If "this event" happens, then "this other event" will happen. A converse statement is one that reverses the order for a conditional statement: If "this other event" happens, then "this event" will happen.
Please watch the conditional and converse statement video.
Please do 3.5 page 204 #4-6, 8-14a.

3.6 - The Inverse and the Contrapositive of Conditional Statements
Both the inverse and the contrapositive of conditional statements are created by writing the negative version of the hypothesis and conclusion. Please watch the inverse and contrapositive video.
