$A$ in the green triangle has the same measure as which angle in the blue triangle?

The green triangle is reflected over the line to create the blue triangle. AngleWhich triangle CANNOT be rotated to create the blue triangle?

$P$ to become the purple figure, how many degrees does it need to rotate?

If the red figure is rotated around pointDo the two figures have a vertical, horizontal, or diagonal line of symmetry?
