# Non-Euclidean Triangle Continuum

Non-Euclidean Triangle Continuum

Triangle is the stereographic projection of a triangle on a sphere tangent to the blue disk at its center. Change the Gaussian curvature of that sphere from to or drag the projected triangle vertices anywhere within the blue disk to obtain a non-Euclidean triangle of any shape. Examine the data for the triangle. Show various triangle centers or the Euler line of the triangle.
