Question

Which transformation most likely shows how the image was created from the preimage?65BС3A2А-3-2-1o25345-1B-2-34Reflection across the line y = x.Reflection across the line y = -2.Rotation of 90° counterclockwise about the origin.Rotation of 180° about the origin.

Answer 1

From the given diagram,

The point A (2 , 2) changes to point A' (-2 , 2)

The point B (-1 , 4) changes to point B' (-4 , -1)

C (4 , 3) changes to point C' (-3 , 4)

By the given data, it is clear that Point (h , k) takes the image of (-k , h)

Thus, the rotation is 90 degree counterclockwise about the origin.

Answer : Option C
