In triangle ABC, PQ drawn parallel to BC meets the side AB at P and the side AC at Q. The lines CP and BQ intersect each other at S. SR drawn parallel to AB meets BC at R. Prove that BR RC = AQ AC<br />
<br />
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
