A 90-degree counterclockwise rotation involves turning an object or point 90 degrees to the left around a specified pivot point. For example, if you imagine a point on a Cartesian coordinate system, moving it 90 degrees counterclockwise would shift its position from, say, (1, 0) to (0, 1). This transformation effectively swaps the x and y coordinates and changes the sign of the new x-coordinate.
It looks like (and is) a rectangle. All angles will be 90 degrees.

The answer will depend on whether the rotation is clockwise or counterclockwise.
You went 360o in the same direction, so you end up with a circle.
Clockwise means turning to your right, counterclockwise is to the left.
what will the letter Y look like if it is turned 90 degrees to the left
(x,y)-> (-y,x)
(-1, -4) rotated 90 degrees anticlockwise
Both will end up on the same place. Using a compass rose as an example: 270 clockwise will point to the west. 90 counterclockwise will also point west.
It looks like (and is) a rectangle. All angles will be 90 degrees.
a L
It is (-1, 6).

A 90-degree angle looks like one corner of a square or a rectangle.
