Creating rectangles and squares
To create a rectangle:

Use the Rectangle Tool ("Shift + F3", or "M").
Click and drag on the canvas to draw a rectangle.
Creating a square
To create a square rather than a rectangle, hold down "Ctrl" while dragging.
Creating and editing rounded corner rectangles
To give your rectangle rounded corners, select it and then press the
"Curved corners" button on the Rectangle Tool
infobar.
You can then drag on the selection handles shown on the corners to adjust the diameter of the rounded
corners.
You can resize rectangles using either the Rectangle Tool (by dragging on the handles shown at the
corners) or the Selector Tool
.
Note that if you change the aspect ratio of a rounded corner rectangle using the Selector Tool
(by stretching it in one dimension only) the aspect ratio of the rounded corners is not stretched, it is
maintained. However if you have multiple objects selected, or if you're stretching a group containing a
rounded corner rectangle, the aspect ratio of the corners is not maintained.
TIP: When rotating rectangles or any shape with straight edges, hold down Ctrl to easily rotate so that
one of the straight edges is exactly horizontal or vertical.
