To reflect triangle ABC over the y-axis, we need to find the new coordinates for each point.

The y-axis is the vertical line passing through the origin (0,0) and extends to the left and right. When reflecting a point over the y-axis, the x-coordinate changes sign while the y-coordinate remains the same.

Given points A=(-1,2), B=(2,1), and C=(4,5), their reflections over the y-axis would be:

A'= (-(-1), 2) = (1, 2)
B'= (-2, 1)
C'= (-4, 5)

So the reflected triangle has points A'=(1,2), B'=(-2,1), and C'=(-4,5).
