The transformations that took place are;
A: BCDE is rotated 180° counterclockwise to form JKLM.
B: BCDE is rotated 180° clockwise to form PQRS.
What is the transformation that took place?
We can see that the coordinates of Rectangle BCDE are;
B(2, 1); C(2, 2); D(4, 2); E(4, 1)
Now, for Rectangle JKLM, we see that the coordinates are;
J(-2, -1); K(-2, -2); L(-4, -2); M(-4, -1).
Now, for Rectangle PQRS, we see that the coordinates are;
P(-2, 1); Q(-2, 2); R(-4, 2); S(-4, 1).
We see the transformation from BCDE to JKLM as (x, y) → (-x, -y) and this is reflection over the x-axis which is 180° counterclockwise.
