WebWith 45-45-90 and 30-60-90 triangles you can figure out all the sides of the triangle by using only one side. If you know one short side of a 45-45-90 triangle the short side is the same length and the hypotenuse is root 2 … WebHowever the general area formula for triangles used in the video (A = 1/2*h*b), works for all triangles, including equilateral ones. Using the special formula as suggested by you would have been quicker though, as you only need to know the side measurement of the equilateral, while the general formula requires the height and the base measurement.

WebWhat are the properties of special right triangles? In a 30-60-90 triangle, the length of the hypotenuse is twice the length of the shorter leg and the length of the longer leg is times the shorter leg. In a 45-45-90 triangle, the length of the hypotenuse is times the shorter leg. WebAngle-based special right triangles are specified by the relationships of the angles of which the triangle is composed. The angles of these triangles are such that the larger (right) …
WebThe ratio of the side lengths of a 30-60-90 triangle is 1 ∶ √3 ∶ 2. This means that if the shortest side, i.e., the side adjacent to the 60° angle, is of length 𝑎, then the length of the side adjacent to the 30° angle is 𝑎√3, and the length of the …
WebFeb 17, 2024 · A special right triangle is a right triangle with angles or sides that make calculations simpler.
