Did you know?
WebWhen dealing with right triangles (triangles that have one 90 degree angle) in trigonometry, the biggest things to realize is that no matter what size the triangle is, the ratios of the lengths of the sides stay the same. So, it is very natural to give these ratios names – and that’s where the right triangle definitions of the trig functions comes from! WebThe three trigonometric ratios; sine, cosine and tangent are used to calculate angles and lengths in right-angled triangles. The sine and cosine rules calculate lengths and angles in any triangle.
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 … WebA special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle. A "side-based" right triangle is one in which the lengths of the sides …
