Use the applet below to create triangles, measure angles and side lengths, to conjecture what properties triangles on a sphere might have. Write these conjectures in the space provided below.
Write as many conjectures as you can about triangles on a spherical plane.
Are there any properties of triangles in the Euclidean plane that do not transfer to the spherical plane? Are there additional conditions we can add to make some of these properties/results true?
