90 clockwise rotation rule
Let’s apply the rule to the vertices to create the new triangle A’B’C’: To rotate triangle ABC about the origin 90° clockwise we would follow the rule (x,y) → (y,-x), where the y-value of the original point becomes the new x-value and the x-value of the original point becomes the new y-value with the opposite sign.

Now that we know how to rotate a point, let’s look at rotating a figure on the coordinate grid.
#90 CLOCKWISE ROTATION RULE FULL#
There are other forms of rotation that are less than a full 360° rotation, like a character or an object being rotated in a video game. The wheel on a car or a bicycle rotates about the center bolt. The earth is the most common example, rotating about an axis. For example, it is a convention that positive real numbers lie to the right of the origin and negative real numbers lie to the left, and no one defines the "right" and "left" of the origin in terms of mathematical concepts.Hello, and welcome to this video about rotation! In this video, we will explore the rotation of a figure about a point. Please note that mathematics conventions are not usually, though depending on the context, formulated mathematically. Please note that your proof is somewhat incomplete.
