Classifying Sides of a Right TriangleDate: 06/12/2002 at 21:00:34 From: Stephanie Subject: trig How do you find the adjacent, hypotenuse, and opposite sides on a triangle? Date: 06/13/2002 at 05:40:14 From: Doctor Jeremiah Subject: Re: trig Hi Stephanie, The opposite side, adjacent side, and hypotenuse are names of sides only for triangles with a right (i.e., 90 degree) angle. If the triangle doesn't have a right angle then the sides cannot use those names. The hypotenuse is the longest side. It is ALWAYS the longest side. The adjacent and opposite sides are relative to whichever angle you are trying to use. The adjacent side is beside the angle you are trying to use and the opposite side is across the triangle from that angle. For example, say you are trying to use angle "a" + |\ | \ | \ | \ | \ | hypotenuse | (longest side) | \ opposite \ (across from a) \ | \ | a \ +------------+ adjacent (beside a) Let me know if this doesn't completely answer your question or if I can help with a different question. - Doctor Jeremiah, The Math Forum http://mathforum.org/dr.math/ |
