It does not classify the triangle. If one side of a triangle is longer than another side, the angle opposite the longer side must be greater than the angle opposite the smaller side. This is true for any triangle. WebWe know that BD is the angle bisector of angle ABC which means angle ABD = angle CBD. Now, CF is parallel to AB and the transversal is BF. So we get angle ABF = angle BFC ( alternate interior angles are equal). But we already know angle ABD i.e. same as angle ABF = angle CBD which means angle BFC = angle CBD. smallest wood stove on the market
