@mpershan It's a generally bright girl who doesn't usually guess. There seems to be a disconnect in applying the angle props to conditionals

@mpershan @MTChirps @MrPoliquin But rules of implication may be at heart of the error rather than knowledge of angles. And maybe guessing.

@MTChirps Does she know that the converse often doesn't follow from the conditional? Maybe she thinks the converse is always trouble.
