The two correct steps are:
1. Reflect △E"F"D" across PR¯¯¯¯¯¯¯¯ so that E"F"¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ maps to QR¯¯¯¯¯¯¯¯.
2. Rotate △E′F′D′ so that D′F′¯¯¯¯¯¯¯¯¯¯¯ maps to PQ¯¯¯¯¯¯¯¯.
For △PQR and △EFD shown, which of the following could be steps to show that the SSS congruence criteria follows from the definition of congruence in terms of rigid motion? Select two correct answers.
A triangle has vertices D, E, and F. Another triangle has vertices P, Q, and R. Sides D F and Q R each have one tick mark. Sides E F and P Q each have two tick marks. Since D E and P R each have three tick marks.
