Question

write the new coordinates after a glide reflection described by. (x,y) (x, y-2) reflection in x=0.

Answer 1

To find the new coordinates, we just have to use the given rule

$(x,y)\rightarrow(x,y-2)$

Let's apply it to each vertex

$\begin{gathered} A(2,10)\rightarrow A^{\prime}(2,10-2)\rightarrow A^{\prime}(2,8) \\ B(3,-4)\rightarrow B^{\prime}(3,-4-2)\rightarrow B^{\prime}(3,-6) \\ C(-3,1)\rightarrow C^{\prime}(-3,1-2)\rightarrow C^{\prime}(-3,-1) \end{gathered}$

Therefore, the new coordinates are A'(2,8), B'(3,-6), and C'(-3,-1).
