In 1–2 sentences, identify what composition transformation maps ΔABC→ΔA"B"C". (coordinates; A(-5, 4), B(-2, 2), C(-1, 5), A'(7, 1), B'(4, -1), C'(3, 2))

Answer 1

The composition transformation that maps ΔABC to ΔA"B"C" involves a translation followed by a dilation. Specifically, the triangle is translated by the vector (12, -3) to move A to A', B to B', and C to C', and then it undergoes a dilation centered at point A' with a scale factor that can be determined by the distance ratios of corresponding points.
