Turtles can only turn or move forward with or without drawing. To draw an arc, you'll need to combine these methods to do that.
I highly recommend the book *Turtle Geometry* by Abelson and diSessa <https://www.amazon.com/Turtle-Geometry-Mathematics-Artificial-Intelligence/dp/0262510375>. Below you can find an excerpt of the book that talks about drawing circles and arcs. [image: turtle.PNG] Here's an implementation of a circle in Racket using the turtle library you referenced. #lang racket (require graphics/turtles) (turtles #t) (for ([i (in-range 360)]) (draw 1) (turn 1)) On Monday, February 1, 2021 at 5:54:05 PM UTC-6 [email protected] wrote: > I am imitating the Logo API to draw some shapes with `graphics/turtles`, > but in it I only find functions to draw lines, is there a way to draw an > arc? > > > > Greetings. > > Killian Zhuo (KDr2, https://kdr2.com) > -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
