Simran wants to draw a square of size 90 without using repeat command give the command to help her.
Answers
Explanation:
This instruction tells Logo to draw four lines, each 100 turtle steps long, and to turn 90 degrees between lines. In other words, it draws a square.
There are many more turtle procedures provided in Logo, but these are the fundamental ones; with them you can go quite far in generating interesting computer graphics. If you haven't had much experience with turtle graphics before, you might enjoy spending some time exploring the possibilities. There are many introductory Logo turtle graphics books to help you. Because that part of Logo programming is so thoroughly covered elsewhere, I'm not going to suggest graphics projects here. Instead I want to go on to consider some of the deeper issues in computer programming that are illuminated by the turtle metaphor.
