Given the vertices of isosceles trapezoid abcd: a(2, 0), b(4, 0), c(5, -2), d(1, -2).
if the image is reflected over the y-axis, then d' =
(1, 2)
(-1, 2)
(-1, -2)
(-2, 1)

D' =(-1,-2)

Therefore, Option 3rd is correct.

Step-by-step explanation:

The  reflection rule is:

When we reflect the point (x,y) along y-axis we will get (-x,y)

When we reflect the point (x,y) along x-axis we will get (x,-y)

Here the coordinate D is (1,-2)

Since, we have to tell after it is reflected along y-axis So, according to the rule

We will get

D' =(-1,-2)

Therefore, Option 3rd is correct.
