Question

I need help with understanding what how to figure this out to do it myself.

Answer 1

We can get B from A, doing the following steps:

Step 1:

Translate A k units up

$(x,y)->(x,y+k)$

Step 2:

Translate A h units left

$(x,y)->(x-h,y)$

Step 3:

Rotate A approximately 45 degrees counter-clockwise:

$\begin{gathered} x^{\prime}=x\cos (45)-y\sin (45) \\ y^{\prime}=x\sin (45)+y\cos (45) \end{gathered}$
