These tools are collectively known as shape tools. Each shape you create displays one or more diamond-shaped handles; try dragging them to see how the shape responds. The Controls panel for a shape tool is another way to tweak a shape; these controls affect the currently selected shapes (i.e. those that display the handles) and set the default that will apply to newly created shapes.
