Theorems: A line drawn parallel to a side of a triangle divides the other two sides proportionally. If two triangles are equiangular then the corresponding sides are proportional. If the three sides of a triangle are proportional to the three sides of another triangle, then the two triangles are equiangular.Geometry Answershttps://www.mathhomeworkanswers.org/225949/solve-the-question-based-on-the-theoremsWed, 07 Sep 2016 15:23:44 +0000What is the exact value of tan eleven and five degree
