To rotate a point around another point in a geometry artboard tutorial

to rotate a point around another point in a geometry artboard tutorial

The specific steps are as follows:

Step one assumes fixed point is a, need to rotate point of B, select "Point Tool" in the artboard blank area draw point A, B; the angle of the mark is the ∠MOP that exists in the drawing area, select the line segment tool to draw any ∠mop in the blank of the artboard.

Step two, double-click Point A, Mark point A as the center of rotation. Select the Marker pen tool, sliding from point O to ∠mop, identifying ∠mop.

Step three selects ∠mop, performs the transform--"Mark angle" command, and marks ∠mop as the rotation angle. Select only fixed-point B, perform "transform"--"Rotate" command, click OK in the pop-up dialog box.

Step four changes the size of the ∠MOP, and point B rotates around point a, so it's done to rotate one point around another by the marker angle.

Above gives you a way to implement a point in a geometric artboard that rotates around another point at a marker angle, primarily to transform the menu with a geometric artboard, marking the ∠MOP as the rotation angle.
