Very simple Trig question about adjacent sides

  1. Jun 13, 2016 #1
    What is the adjacent side to an angle at 90 degrees? Aren't two sides adjacent to it?

    Yes, but the usual context is that we're interested in one of the acute angles in a right triangle, not the right angle.

    There's two adjacent sides to every angle.

    Lol, well yes, but what I meant to say was, and what I think was implied was, "Aren't there two adjacent sides, neither of which are the hypotenuse?"

    Consider what happens if you start with an angle less than 90 and then increase it so that it approaches 90.
