Question

triangle p has coordinates (0,), (2,0), (0,4) triangle q has coordinate (0,0), (4,0),(0,8) which transformation maps triangle p onto triangle q reflection across the x-axis a rotation followed by a reflection a dilation with scale factor 2 or a translation only

Answer 1

Triangle P: (0,0), (2,0), (0,4).
Triangle Q: (0,0), (4,0), (0,8).

Each vertex of P is doubled to get Q: (0,0)→(0,0), (2,0)→(4,0), (0,4)→(0,8). So the transformation is a dilation by scale factor 2 centered at the origin.
