A triangle, △ABC, is drawn with a circumscribed circle centered at point D. Radius DE¯¯¯¯¯¯¯¯ is drawn perpendicular to AB¯¯¯¯¯¯¯¯ so that point E is on the circle. If DA¯¯¯¯¯¯¯¯ and DB¯¯¯¯¯¯¯¯ are drawn, which of the following statements must be true? DA¯¯¯¯¯¯¯¯⊥DB¯¯¯¯¯¯¯¯ △AED≅△BED DA¯¯¯¯¯¯¯¯∥DB¯¯¯¯¯¯¯¯ Both △AED and △BED are scalene triangles.
