    So @Greedy_Bee and I just had a random conversation about geometry with it's proofs and stuff. So here is a conditional (p => q) statement and what I want you to do is come up with its converse (q => p), inverse, (~q => ~p) and its contrapositive (~p => ~q) and figure out if the statement is true or false. Remember, if you haven't taken geometry yet, this may be a little bit hard to you.

    Ready?
    And Greedy_Bee, please don't give the answer :smile:

    If GTA 5 comes out, then terdd loses his social life.

    That's the conditional statement. If the correct answer isn't posted by tomorrow first thing when I log onto the forums, then I'll post it correct.

    There may or may not be a prize...

    If P, then Q - If GTA 5 comes out, then terdd loses his social life.
    If Q, then P - If terdd loses his social life, then GTA 5 has come out.
    If -P, then -Q - If GTA 5 has not come out, then terdd has not lost his social life.
    If -Q, then -P - If terdd has not lost his social life, then GTA has not come out.

    Honors Geometry I believe. Teacher said we'd learn Trig but not in depth.

    There we go. I know my math classroom has a poster with that but it doesn't tell each letter's meaning.
