About shapes
Shapes are objects that can be resized, rotated, flipped, colored, and combined. Many shapes have an adjustment handle that you can use to change the most prominent feature
AutoShapes , on the Objects toolbar, contains several types of shapes, including lines, connectors, basic shapes, block arrows, flowchart elements, stars and banners, and callouts.
Text can be added to shapes. The text you add becomes part of the shape
Note Text boxes can be treated as shapes. You can resize, rotate, flip, color, and combine them just as you would shapes.
