A 90-degree rotation involves turning an object or point around a fixed pivot point, such as the origin in a coordinate system, by a quarter turn. In a clockwise direction, for instance, the point (x, y) would move to (y, -x), while in a counterclockwise direction, it would move to (-y, x). This transformation changes the orientation of the object without altering its shape or size.
A 90 degree rotation is a quarter of a turn.
To find the image of the point (4, 3) after a -90-degree rotation (which is equivalent to a 90-degree clockwise rotation), you can use the rotation formula: (x', y') = (y, -x). Applying this to the point (4, 3), the new coordinates become (3, -4). Therefore, the image of the point (4, 3) after a -90-degree rotation is (3, -4).

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

plz awnser this
A bisected 90 degree angle
Yes, a 270-degree clockwise rotation is the same as a 90-degree counterclockwise rotation. When you rotate an object 270 degrees clockwise, you effectively move it 90 degrees in the opposite direction, which is counterclockwise. Both rotations will result in the same final orientation of the object.

An example of a 90 degree angle is any of the four corners of an A4 page.
It looks like (and is) a rectangle. All angles will be 90 degrees.
90 degree anticlockwise.
