For questions 1,2,4,5,8 & 9, use the contracts provided to find expressions that will generate images similar to the ones pictured.
Test your code in code.pyret.org (CPO) before recording it.

The numbers used in student code will vary, but should have relationships proportional to the ones shown in the solutions.

# ellipse :: (Numberwidth, Numberheight, Stringfill-style, Stringcolor) -> Image

1

black outline of an ellipse that’s about 3 times as tall as it is wide

2

solid black ellipse that’s about 3 times as wide as it is tall

3

Write an expression using ellipse to produce a circle.

# regular-polygon :: (Numberside-length, Numbernumber-of-sides, Stringfill-style, Stringcolor) -> Image

4

solid black pentagon

5

black outline of an octagon

6

Use regular-polygon to write an expression for a square!

7

How would you describe a regular polygon to a friend?

# rhombus :: (Numbersize, Numbertop-angle, Stringfill-style, Stringcolor) -> Image

8

solid black rhombus, wider than it is tall

9

black outline of a rhombus, taller than it is wide

10

Write an expression to generate a rhombus that is a square!
