Best ResponseYou've already chosen the best response.1In two triangles i.e. triangle ABC and triangle DEC , angle BAC=angle DEC=90 degrees , angle BCA=angle DCE=vertically opposite angle, and line BC=line CD (given line DB bisects line AE). So by AAS(angle angle side) congruence condition these two triangles are congruent and hence, line BC=line DC so C is the mid point of line BD
