x.Notice that the triangle is inscribed in a circle of radius 1. Such a circle, with a center at the origin and a radius of 1, is known as a unit circle. Figure 1. We can define the trigonometric functions in terms an angle t and the lengths of the sides of the triangle. The ...
In other words, it is the smallest circle that the triangle can fit inside of. It’s equal to 2/3 the height, or twice the value of the inradius. R = 2r The circumradiusRis equal to 2 times the inradiusr You might also be interested in ourright triangle calculator. ...
