CMU CS Academy 1.3.1 Rectangles, Ovals, Circles, and Lines

To draw an oval (also called an ​ (a)   ), we use the ​ (b)   instead of the left-top, but then we still use the width and ​ (c)   , like so:

​ (d)   ( 150, 150, 100, 200, fill='gold' )

Ovals, like most shapes, ​ (a)   borders, ​ (b)   , gradients, and other properties that ​ (c)   have!

Circles are drawn just like ovals, only instead of ​ (a)   we just use a ​ (b)   . So we draw a circle centered at (100, 200) with a radius of ​ (c)   like so:

​ (d)   ( ​ 100, 200, 50, fill='green')

A line runs from ​ (a)   (x1, y1) to ​ (b)   (x2, y2). We include those points when drawing a line. So we draw a line from (50, 100) to (75, 200) like this:

​ (c)   (50, 100, 75, 200)

Use the Inspector and see how it ​ (d)   of the line. Useful!

Lines do not have a borderWidth. It is an error to set the borderWidth of a line. Instead, use ​ (a)   . Like borders, lines can also have ​ (b)   by setting dashes=​ (c)   or dashes=(dashWidth, gapWidth).

Where is the circle centered in the example?

What do we use to draw a circle instead of width and height?
