How to make the drawn circle have part of the dotted line in the geometric sketchpad

When using the geometric sketchpad to draw a circle, you often need to set a part of the circle as a dotted line. PHP editor Apple will provide you with a solution to this problem. The method has simple steps and is easy to use. Please read below for detailed steps.

Draw a circle. To make part of the circle represented by a dotted line, you need to construct the circle first. Open the Geometry Sketchpad. On the left toolbar, there is a ready-made [Circle Tool]. This tool replaces the traditional compass and can be used to draw circles. Select the [Circle Tool], click on the drawing board to determine the center position of the circle, drag the mouse to determine the size of the circle and click the mouse again to draw the circle.

If you want to make part of the circle a dotted line, the premise is that this part is separate, so you need to construct an arc on the circle. Select [Point Tool] on the left sidebar, pick two points A and B on the circle, these two points are free points, then select the center of the circle, point B, and point A in sequence, click the [Construct] menu on the upper menu bar, and click Select the [Arc on Circle] command from the drop-down option.

Draw a dotted line on the circle. After executing the above command, the arc AB on the circle will be constructed. Except for the part of arc AB, the rest will be displayed as a dotted line to distinguish it from the arc AB. In this way, a dotted line is drawn on the circle.

If you want to display the other half of the circle with a dotted line, the order of selecting points is a little different from the above. Select the center of the circle, point A, and point B in order, so that the other half becomes a dotted line.
