Another way to use this triangles is to put in the general Pythagorean theorem With this, you can also calculate the values of a side in a triangle given other sides of the same right angle triangle How is triangles solved?A triangle is one of the few special right triangles with angles and side ratios that are consistent and predictable Specifically, every triangle has a 30º angle, a 60º angle, and a 90º angle Since these angles stay the same, the ratio between the length of the sides also remains the sameWatch more videos on http//wwwbrightstormcom/math/geometrySUBSCRIBE FOR All OUR VIDEOS!https//wwwyoutubecom/subscription_center?add_user=brightstorm2VI
