The rotation matrix for a 90° rotation is [[0,-1],[1,0]]
More simply, if our shape is a function of x and y, we swap x and y and then negate y.
For instance: if our function is y=x, then the 90° rotation would be x=-y
Rotating a figure 270 degrees is like rotating the figure to the left 90 degrees. I am not sure what formula or rule you use. *Joe Jonas Rocks*
A Right Isosceles Triangle is a shape that has one 90° angle. 90 degrees + the other two angles add up to 180 degrees.

It is a right angle

"East" is a directional term that refers to the direction you would face when observing the sun rise. It can also be found by rotating 90 degrees clockwise from north, or by rotating 90 degrees counterclockwise from south.
A Right Isosceles Triangle is a shape that has one 90° angle. 90 degrees + the other two angles add up to 180 degrees.
A restangle can be it but it has 4 angles at 90 degrees.
0
It is a right angle
L shape
Any shape that has more than 4 sides has all angles bigger than 90 degrees.

To rotate a figure 270 degrees counterclockwise about the origin, you can achieve this by rotating it 90 degrees clockwise, as 270 degrees counterclockwise is equivalent to 90 degrees clockwise. For each point (x, y) of the figure, the new coordinates after the rotation will be (y, -x). This transformation effectively shifts the figure to its new orientation while maintaining its shape and size.
