Question

I need help with this hw

Answer 1

$\begin{gathered} \angle B\cong\angle D \\ \angle B=2\tan ^{-1}(\frac{2}{2})=90 \\ \angle D=2\tan ^{-1}(\frac{-2}{-2})=90 \end{gathered}$

After a reflection across x-axis:

$\begin{gathered} \angle B=2\tan ^{-1}(\frac{-2}{2})=90 \\ \angle D=2\tan ^{-1}(\frac{2}{-2})=90 \end{gathered}$

After a reflection across y-axis:

$\begin{gathered} \angle B=2\tan ^{-1}(\frac{-2}{-2})=90 \\ \angle D=2\tan ^{-1}(\frac{2}{2})=90 \end{gathered}$
