How to Insert Shapes in an Excel 2010 Worksheet
You can insert graphic shapes such as lines, rectangles, block arrows, stars, and other basic shapes in your Excel 2010 charts and worksheets. All you need to do is select a thumbnail on the Shapes drop-down gallery on the Insert tab of the Ribbon and draw the shape in the worksheet.
1On the Insert tab, click the Shapes button in the Illustrations group.
The Shapes gallery appears, revealing nine categories of shapes, including Recently Used Shapes at the top.
2Click a shape thumbnail to select it.
The Shapes gallery disappears and the mouse pointer changes to a crosshair.
3Click and drag the mouse in the worksheet to create the shape in the desired size.
Drag the object until it’s approximately the size you want (you can fine-tune the size later).
4Release the mouse button.
The shape appears in the worksheet.
