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
righttriangle:: (base::Number, height::Number, style::String, color::String) > Image
isoscelestriangle:: (leg::Number, angle::Number, style::String, color::String) > Image
2 Why do you think triangle only needs one number, while righttriangle and isoscelestriangle need two numbers and trianglesas needs three?
3 Write righttriangle expressions for the images below. One argument for each should be 100
.
4 What do you think the numbers in righttriangle represent?
5 Write isoscelestriangle expressions for the images below. 1 argument for each should be 100
.
6 What do you think the numbers in isoscelestriangle represent?
7 Write 2 expressions that would build rightisosceles triangles. Use righttriangle for one expression and isoscelestriangle for the other expression.
