Consider the statement:

Write the statement in the following forms:

If I'm in math class, then I am having fun.

If I'm in math class, then I am having fun.

08. Inverse and Contrapositive ­ Day 2.notebook March 26, 2013

If a conditional statement is true, then its contrapositive is true, and vice­versa.

If the inverse of a conditional statement is true, then the converse of the statement is also true, and vice­versa.
