How do I make the dots in the drawings in unit 3 lesson 2?

I am doing this lesson which I think we did in Phoenix, but I don’t remember how to get the black dots in the circles.


There actually are no black dots in the circles - the black dots in the middle of the circle (oval) is a reference point to the origin (when you give it x and y that’s where it begins). Same thing for the rectangle (square) but in the top left corner.

Let me know if you have further questions!
