Q Look at the polygon on the right.
The coordinates of its vertices are:
D(-4,3) E{3,3) F(3, 1) G(-2, 1) H (-3, 0)
Where will the vertices of the image of polygon DEFGH
be after we reflect the polygon in the x-axis?
Q For each reflection, state the axis about which the object is reflected.
a) >' b)
> X
