Question

Reflect parallelogram FGHJ across the line x = 4 and identify the newcoordinates for F'.(4.1)16.1)(2.7)0 12.4)

Answer 1

Let:

`\begin{gathered} G(7,1) \\ H(6,-3) \\ J(1,-3) \\ F(2,1) \end{gathered}`

After a reflection across the line x = 4:

`\begin{gathered} G\to(x-2\Delta x,y)\to G^(\prime)=(7-6,1)=(1,1) \\ H\to(x-2\Delta x,y)\to H^(\prime)=(6-4,-3)=(2,-3) \\ J\to(x+2\Delta x,y)\to J^(\prime)=(1+6,-3)=(7,-3) \\ F\to(x+2\Delta x,y)\to F^(\prime)=(2+4,1)=(6,1) \end{gathered}`
