InterviewSolution

1.	BE and CF are two equal altitudes of a triangle ABC. Using RHS congruence rule, prove that the triangle ABC is isosceles.
Answer» BE=CF `angleBEC=angleCFB=90^0` In `/_BFC and /_CEB` `angleBEC=angleCFB=90^0` BC=BC BE=CF `/_BFCcong/_CEB` `angleFBC=angleECB` In `/_ABC and angleACB=angleABC`----> isosceles AB=AC.
