Microsoft PowerPoint has drawing tools.  The drawing tools include ready-made shapes called AutoShapes, lines, boxes, ovals, textboxes, Word art, clipart.  You can also use it to add borders, fills, shading and shadows to the graphic objects.  These graphic images are used to enhance the programmes.

Check if there's a Draw tool bar on the screen. The toolbar is often positioned at the bottom of the screen.  See below for the options it provides.

If the Draw tool bar is not visible, Click on View, then Toolbars, then Drawing to turn it on.
