Question

What are the coordinates of D' when the quadrilateral is reflected across the line y = X?

Answer 1

`D' = (1,3)`

Explanation:

Given

See attachment

Required

Find D'

From the attachment, we have:

`D = (3,1)`

When reflected across y = x.

The rule is:

`(x,y) \ to (y,x)`

So, if
`D = (3,1)`

Then:

`D' = (1,3)`
