The Cosine Rule – Explanation & Examples - Story of Mathematics

WebThe hypotenuse is the longest side of a right triangle. It is always the side opposite the right angle. Since your 30-30-120 triangle doesn't have a right angle, it is not a right triangle, therefore it does not have a hypotenuse. Having said that, if you want to know the measure of the longest side of your triangle, even though it isn't called ... 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 …
