Chapter 14: Problem 23

When using a Graphics object to draw an oval, what invisible shape is the oval enclosed in?

Short Answer

Expert verified
Answer: The invisible shape enclosing an oval drawn with a Graphics object is a rectangle.

Step by step solution

01

Understand the Graphics object

A Graphics object is a component of many programming environments, such as Java, that allows the creation and modification of shapes, icons, and images. In this case, the Graphics object is being used to draw an oval.
02

Identify the invisible shape enclosing an oval

When drawing an oval with a Graphics object, the invisible shape enclosing the oval is a rectangle. This rectangle provides the boundary for the oval's width and height.
03

Explain why the invisible shape is a rectangle

The reason why the invisible shape is a rectangle is because the Graphics object uses a method called drawOval, which requires four parameters: x-coordinate, y-coordinate, width, and height. The x and y coordinates represent the top-left corner of the invisible rectangle, while the width and height represent the size of the rectangle. The oval is drawn within this rectangular area, touching the midpoints of the sides of the rectangle.
04

Visualize the invisible rectangle

To help you visualize this concept, imagine a sheet of graph paper. Place the oval on the paper so that its maximum width and height are aligned with the gridlines. The rectangle is formed by connecting the points where the oval touches the gridlines with straight lines.
