Question

Graph the reflection of the polygon in the given line #11

Answer 1

Let:

`\begin{gathered} A=(2,-1) \\ B=(-1,2) \\ C=(2,3) \\ D=(4,2) \end{gathered}`

After a reflection across the line y = x:

`\begin{gathered} A->(y,x)->A^(\prime)=(-1,2) \\ B->(y,x)->B^(\prime)=(2,-1) \\ C->(y,x)->C^(\prime)=(3,2) \\ D->(y,x)->D^(\prime)=(2,4) \end{gathered}`
