To find the 6 ratios for angle B, just start over again and rethink them looking at angle B instead of angle A. This means that the opposite and the adjacent sides switch while the hypotenuse stays the same.

To get started, try working from the example problem already populated in the box below. Remember, if you're working on homework your teacher isn't stupid -- he or she knows if you're just using a calculator! So obey his or her instructions and do your own work if asked.
