Triangle Inequality Theorem Worksheets. TRIANGLE SUM THEOREM WORKSHEET 1. Geometry Worksheets | Triangle Worksheets - Math-Aids.Com This Triangle Worksheet will produce triangle angle sum problems. Example: In the figure below, PQ PR , and PS and ST are medians. In any triangle, there are always three interior angles. Prove that the sum of the measures of the interior angles of a triangle is 180. <>
This is a coloring activity for a set of 12 problems on the exterior angle sum theorem. We can still use the fact that they have to add to 180to figure this out. Triangle angle sum In any triangle, there are always three interior angles.
