Question

I need help with this hw

Answer 1

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

After a reflection across x-axis:

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

After a reflection across y-axis:

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