Question

The vértices of GHI are G(-4,0), H(5,2), and I(-2,-3) . GHI is rotated 270 counterclockwise about the origin to form GHI. What are the coordinates of the vertices of GHI?

Answer 1

Answer:

To find vertices that has been rotated 270 degrees, you would want to apply this rule to the point ; (x,y) (x, -y). This rule is the same as negative 90 rotation.

So, we have the coordinates (-4,0) , (5,2) , (-2,-3).

We can apply the rule to all three coordinates turning the y values negative.

We end up with

G = (-4, 0)

H = (5, -2)

I = (-2, 3)
