Rectangle('Position',pos,'Curvature',cur) adds curvature to the sides of the rectangle. For different curvatures along the horizontal and vertical sides, specify cur as a two-element vector of the form horizontal vertical. For the same length of curvature along all sides, specify cur as a scalar value. Specify values between 0 (no curvature) and 1 (maximum curvature). Home Math Geometry Geometry Proofs Prove it is a Rectangle. Prove it is a Rectangle. It is possible to prove that a quadrilateral is a rectangle. Before we get started with the proofs, let's review what is special about rectangles. First, we know that rectangles are parallelograms, so. Explanation: The given rectangle has a length that is units longer than its width. This can be expressed in the following equation, where is the length and is the width of the rectangle. Since the area of the rectangle is equal to its length multiplied by its width ( ), and the area of the rectangle is given, the following equation must be true. Replacing in this equation with its value stated in the first equation results in the following. The term rectangle comes from the Latin rectangulus that is a combination of two words: rectus (right, proper) and angulus (angle). This name derives from the fact that a rectangle is a quadrilateral with four right angles (4. 90° = 360°).

Example
The following example shows how to create and render a RectangleGeometry. The relative position and the dimensions of the rectangle are defined by a Rect structure. The relative position is 50,50 and the height and the width are both 25 creating a square. The rectangle's interior is painted with a LemonChiffon brush and its outline is painted with a Black stroke with a thickness of 1.

Rectangle Geometry Problems
Although this example used a Path element to render the RectangleGeometry, there are many other ways to use RectangleGeometry objects. For example, a RectangleGeometry can be used to specify the Clip of a UIElement or the Geometry of a GeometryDrawing.
Other simple geometry classes include LineGeometry and EllipseGeometry. These geometries, as well as more complex ones, can also be created using a PathGeometry or StreamGeometry.
