Use Pythagorean Theorem
in a right triangle. |
Our friend, the
Pythagorean Theorem, comes to our aid when solving for sides
and/or angles in a right triangle. We have now seen that
there are formulas (the Law of Sines and the Law of Cosines)
that will help us find sides and/or angles when we are not
working in a right triangle.
But where did these formulas
come from? |
