- Select a shape and place it on your slide (I selected an oval). Resize it as you want.
- With the shape selected, go to Drawing Tools ribbon, Format tab.
- Click Edit Shape from Insert Shapes group and select Convert to Freeform.
- Repeat step 3 but this time select Edit Points. You will see the shape will have multiple points for you to adjust.
- Now you can drag any edge of your shape to form a new shape of your own.
