Question

in the diagram, which transformation makes triangle 2 the image of triangle 1? 1 reflection in the y - axis 2 dilation 3 translation 4 rotation centered at the origin

Reflection flips over a line, dilation changes size, translation slides, rotation turns.

Step2: Analyze the diagram

Triangles have same size and shape, just mirrored across y - axis.

Answer:

1. reflection in the y - axis
