About Drawing

Drawing also provides functions that allow you to perform a variety of mathematical

calculations on rectangles--changing their sizes, shifting them around, and so on.

An **oval** is a circular or elliptical shape defined by the bounding rectangle that

encloses it. If the bounding rectangle is a square (that is, has equal width and

height), the oval is a circle, as shown in Figure 13-3.

An** arc** is a portion of the circumference of an oval bounded by a pair of radii

joining at the oval's center; a wedge includes part of the oval's interior. Arcs and

wedges are defined by the bounding rectangle that encloses the oval, along with a

pair of angles marking the positions of the bounding radii, as shown in Figure 13-4.
