move the spite using arrow keys, click the sprite in the top right corner to select shape, press space to make the selected shape. Feel free to remix as long as u give credit :)
NOTES - the circle takes a bit of time to generate, the sprite will always be at the top right hand corn of the shape (excluding triangle and line) CREDITS - equilatoral triangle part from https://www.google.com/search?q=how+to+make+an+equilateral+triangle+in+scratch&rlz=1C1CHBF_enUS893US893&sxsrf=ALeKk01j0E6J0VdqFLM-ZoeFnT9G9kaAtg%3A1620587222634&ei=1jKYYOqjJvC_0PEP0P286A8&oq=how+to+make+an+equilateral+triangle+in+sratc&gs_lcp=Cgdnd3Mtd2l6EAEYADIECAAQDToHCAAQRxCwAzoHCAAQsAMQQzoECAAQQzoCCAA6BggAEBYQHjoFCCEQoAE6BwghEAoQoAFQqQdYz0Vg7VFoBXACeACAAaADiAGdF5IBCTAuMi44LjEuMZgBAKABAaoBB2d3cy13aXrIAQrAAQE&sclient=gws-wiz#kpvalbx=_DDOYYK7UHZH19APspLiYBw29, circle part from @footsocktoe's post on this discussion https://scratch.mit.edu/discuss/topic/240126/?page=1#post-2452891
