The ppt2010 edition uses the shape to edit the vertex function to design the circular arc effect picture and text course

First, insert a rectangle in the PPT, select the shape rectangle in the Insert tab, and draw

Right-click to set shape format, choose the effect you want, here I chose a solid color fill, no Line color

The resulting effect is as shown

Double-click the graphic, the menu bar Insert shape has an edit shape, click to select the edit vertex, then the graphic will appear around the black box

Hold down the black square to the freeform (right-click to add or remove vertices), press Ctrl+shift to copy pictures vertically

Attention matters

Be patient with this.
