A: The triangles are similar. We know this because of the AA similarity theorem. Angle C and F are both right angles. All right triangles are congruent (Definition of Right Angle) Angle BDC is congruent to angle EDF(Reflexive Property)
B: BC<span> corresponds</span> to EF. This is known because BD is part of ED making them correspond and DC is a part of DF making them correspond. Leaving BC and EF(there are many reasons for it).
C: Angle C corresponds to angle F because 1 they are both right angles and 2 See answer B.
