Help Please I will give brainliest and 16 points!!!

Step-by-step explanation:

When you rotate points of a figure 180° about the origin, every x-value and y-value is switched to its negative.

For example, (x, y) => (-x, -y).

E(1, 2) => E'(-1, -2)

F(1, 3) => F'(-1, -3)

G(4, 3) => G'(-4, -3)

H(4, 2) => H'(-4, -2)
