Question

Triangle ABC has vertices at A(-3, 5), B(0, 0), and C(6, 5). It is transformed so that Triangle A'B'C' has coordinates A'(1, 11), B'(4, 6), and C'(10, 11).

Jacob says that the transformation was an x-axis reflection. Is he correct? Explain.

Answer 1

Jacob is incorrect. The transformation was no a reflection, but a translation. The transation was (x+11,y+6)(11 units rigth and 6 units up). (Explain what the points would have been if it was a reflection across the x-axis)
