WebStep-1:Construction: Draw altitude A E perpendicular to B C. Step-2: Express A E in terms of A B: Consider right angled A E B with right angle at vertex E. By applying Pythagoras theorem. A E 2 + E B 2 = A B 2. ⇒ A E 2 = A B 2 - E B 2. In an equilateral triangle, the altitude bisects the opposite side i.e. E B = B C 2 = A B 2 ∵ A B = B C. WebIntroduction & Formulas. The Angle bisector theorem states that given triangle and angle bisector AD, where D is on side BC, then .It follows that .Likewise, the converse of this theorem holds as well.. Further by …
