1 What kind of triangle does the triangle function produce?
There are lots of other kinds of triangles! And Pyret has lots of other functions that make triangles!
triangle:: (size:: Number, style :: String, color :: String) -> Image
right-triangle:: (base::Number, height::Number, style::String, color::String) -> Image
isosceles-triangle:: (leg::Number, angle::Number, style::String, color::String) -> Image
2 Why do you think triangle only needs one number, while right-triangle and isosceles-triangle need two numbers and triangle-sas needs three?
3 Write right-triangle expressions for the images below. One argument for each should be 100.
4 What do you think the numbers in right-triangle represent?
5 Write isosceles-triangle expressions for the images below. 1 argument for each should be 100.
6 What do you think the numbers in isosceles-triangle represent?
7 Write 2 expressions that would build right-isosceles triangles. Use right-triangle for one expression and isosceles-triangle for the other expression.
