During the process of using the geometric sketchpad, some friends expressed that they wanted to construct a midpoint trajectory between a point on the circle and any point, but they did not understand the related operations. What should they do? The editor below will explain how to construct the midpoint trajectory between a point on a circle and any point on the geometric sketchpad. I hope it can help you.

Construct a circle O and pick a point A on the circle. Open the geometric sketchpad, select the "Circle Tool" on the left sidebar and draw a circle O in the work area. Use the "Point Tool" to pick a point A on the circle.

                                                                                                                                                                                                                          Pick a point B and construct a line segment AB. Use the "Point Tool" to draw a point B arbitrarily in the blank area, select points A and B in turn, click the "Construction" menu on the upper menu bar, and select the "Line Segment" command from its drop-down option, thus constructing the line segment AB.

Construct the midpoint M of line segment AB. Use the move tool to select line segment AB, click the "Construction" menu on the upper menu bar, and select the "Midpoint" command from its drop-down option, thus obtaining the midpoint M of the line segment.

                                                                                                                                                                                                                                                                    a       Use the move tool to select point A and point M in sequence, click the "Construction" menu in the upper menu bar, and select the "Trajectory" command from its drop-down option, thus obtaining the motion trajectory of midpoint M.
