Learning Objectives

In this challenge we are going to use x and y coordinates to draw shapes on the screen. We will be using the turtle library to draw on the screen.

X and Y coordinates? Quadrant?

Check the above picture. Can you state three facts about X and Y coordinates and about quadrants?

The canvas we are drawing on (using Python Turtle) is 400 pixels wide by 400 pixels high.
Look at the canvas below to understand how (x,y) coordinates work:
