WebSep 12, 2024 · This “triangle” has an angle sum of 90+90+50=230 degrees! Figure 9.5. 1: On a sphere, the sum of the angles of a triangle is not equal to 180°. The surface of a sphere is not a Euclidean plane, but locally the laws of the Euclidean geometry are good approximations. In a small triangle on the face of the earth, the sum of the angles is very ... WebFeb 10, 2005 · The third one has some angle measurement too but I think that suffices to prove the sum of the interior angles is greater than 180 degrees. If you're still a little shaky because I told you how to make a specific triangle, try moving the first two lines closer together: Sure one angle gets smaller but the other two stay the same at 90 degrees, so …
