One way to create a unique shape is to reshape the contours of a predrawn shape after you’ve placed it on the slide canvas. This technique can also be used to readjust the curves of a custom shape.
Make the shape editable. To learn how, see Making Shapes Editable.
Red points appear on the shape, indicating that you can reshape the curves at these points.
Click a red point on the curve you want to reshape. Handles appear on both sides of the red point.
To adjust the curvature, drag the red point or one of its handles.
Move the control handles clockwise or counter-clockwise. Different effects result when you move the handles together or independently of each other. Experiment until you achieve the desired effect.
To move the handles together, press the Option key, and then drag either one of them.
To move only one handle, press the Command key while dragging it.
For more precise control of the contour, add more editing points by holding down the Option key while you hold the pointer along the shape’s border. When the pointer takes the shape of a pen tip with a plus (+) sign, click where you want to add a new editing point. For more information, see Adding, Deleting, and Moving the Editing Points on a Shape.
