Right triangle trig functions
WebThe ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined … WebWhen using similar triangles, their sides are proportional. If two triangles have two congruent angles, then the triangles are similar. So, if you have a 30-60-90 triangle then the sine ratio …

WebMar 5, 2024 · Example 5.2.1: Find trigonometric ratios given 3 sides of a right triangle. Given the triangle shown, find the value for cos(α). The side adjacent to the angle is 15, and the hypotenuse of the triangle is 17, so. cos(α) = adjacent hypotenuse = 15 17. Try It 5.2.1. WebTrigonometry comes from the two roots, trigonon (or “triangle”) and metria (or “measure”). The study of trigonometry is thus the study of measurements of triangles. What can we measure in a triangle? The first objects that come to mind may be the lengths of the sides, the angles of the triangle, or the area contained in the triangle. We first explore …
