Hello Jacque. So, for a statement "If P then Q" we have three definitions:
Converse: If Q then P.
Inverse: If not P then not Q.
Contrapositive: If not Q then not P.
In this case we have P="If an angle is obtuse" and Q="it measures more than 90 degrees." And so we have
Converse: If an angle measures more than 90 degrees then it is obtuse.
Inverse: If an angle is not obtuse, then it does not measure more than 90 degrees.
The converse I think I will let you try on your own, but if you get stuck feel free to reach out; I would be happy to help. Hopefully this clears things up. Again, let me know if you have any other questions. Thank you for your time and have a wonderful day!
