The basic trig functions are defined as ratios of the sides of the triangle as the legs relate to θ (either adjacent to it or opposite it). You need to memorize these!!! They are pronounced: sin(θ) = “sine theta” cos(θ) = “cosine theta” tan(θ) = “tangent theta” For the right triangle …

Using the Pythagorean theorem (a2+b2=c2), we can find the 3rd side of a triangle if we know the other two sides and if we know we have a right triangle. If we use trig functions as well (assuming we still have a right triangle), we can find any angle or any side as long as we have two angles, two sides, or an angle and a side (aside from the ...
