Question

A triangle has vertices at a (2,4) b (4,3) c (5,7) which transformation would produce an image with vertices a' (-2,-4) b' (4,-3) c' (-5,-7) does this reflect over y axis or x axis or rotate 180 or 90 degrees

Answer 1

180° rotation

Explanation:

The triangle and its image are shown below.

The image is formed by a 180° rotation about the origin, every coordinate is inverted, that is, (x, y) ⟶ (-x, -y).

It is not formed by a 90° rotation or by a reflection across either axis.
