THE 30°60°90° TRIANGLE THERE ARE TWO special triangles in trigonometry One is the 30°60°90° triangle The other is the isosceles right triangle They are special because, with simple geometry, we can know the ratios of their sides Theorem In a 30°60°90° triangle the sides are in the ratio 1 2 We will prove that belowThe measures of its angles are 30 degrees, 60 degrees, and 90 degrees And what we're going to prove in this video, and this tends to be a very useful result, at least for a lot of what you see in a geometry class and then later on in trigonometry class, is the ratios between the sides of a triangleNow when we are done with the right triangle and other special right triangles, it is time to go through the last special triangle, which is 30°60°90° triangle It also carries equal importance to 45°45°90° triangle due to the relationship of its side It has two acute angles and one right angle What is a Triangle?

General triangle rule () Post by tgf » Sun Nov 29, 09 1051 am Hi, if a right triangle has one angle equal to 30 (or 60) you KNOW the other angle has to be 60 (or 30) and thus the longest side is 2 times the shortest sideWhat is a Triangle?Right triangles are one particular group of triangles and one specific kind of right triangle is a right triangle As the name suggests, the three angles in the triangle are 30, 60, and
Using the triangle to find sine and cosine Before we can find the sine and cosine, we need to build our degrees triangle Start with an equilateral triangle with a side length of 4 like the one you see belowRight Triangle Calculator Although all right triangles have special features – trigonometric functions and the Pythagorean theorem The most frequently studied right triangles , the special right triangles, are the 30, 60, 90 Triangles followed by the 45, 45, 90 trianglesWatch more videos on http//wwwbrightstormcom/math/geometrySUBSCRIBE FOR All OUR VIDEOS!https//wwwyoutubecom/subscription_center?add_user=brightstorm2VI
