Question

Trapezoid JKLM has points J(-2,4), K(2,-4), L(4,2), and M(-4,2). Which transformation will map the trapezoid to itself? a. reflection across the x-axis b. reflection across the y-axis*** c. rotation of 90 degree about the origin and d. rotation of 180 degrees about the origin

Answer 1

I can't tell, but it looks like you chose b. I don't agree with this answer. Did you draw the trapezoid out on graph paper?

Answer 2

If you write out the points, then provide the mapping rules, you can check each new rule...
You may have missed a negative sign in your original stating of the points :)
