ΔA'B'C' was constructed using ΔABC and line segment EH. 2 triangles are shown. Line E H is the line of reflection. Line segment B B prime has a midpoint at point D. Line segment A A prime has a midpoint at point F. Line segment C C prime has a midpoint at point G. For to be the line of reflection between and , which statements must be true? Select three options. BD = DB' DF = FG m∠EFA = 90° The line of reflection, EH, is the perpendicular bisector of BB', AA', and CC'. ΔABC is not congruent to ΔA'B'C'.
