Trigonometric ratios in right triangles (video) | Khan Academy
So if you're trying to find the trig functions of angles that aren't part of right triangles, we're going to see that we're going to have to construct right triangles, but let's just focus on the right …
Intro to the trigonometric ratios (video) | Khan Academy
Sin, cos, and tan are trigonometric ratios that relate the angles and sides of right triangles. Sin is the ratio of the opposite side to the hypotenuse, cos is the ratio of the adjacent side to the …
Right triangle trigonometry review (article) | Khan Academy
Say you had a question with an upright right triangle, angles ∠ A ∠B and∠ C with the right angle at A. You know both the angle measures of b and c, and you're using cos.
