Alright, let's first identify what complementary is okay? They can be complementary or supplementary, comp is two angles that equal 90 degrees while supp is two angles that equal 180 degrees.

I already understand what complementary and supplementary mean I just don't understand it in this context.

benji · Answer

Well the third and last option are not rational, since all angles are not right angles, and just because they are comp does not mean they are congruent.

I still can't pick or choose between A or B.

benji · Answer

I think it's A.
