help in 2d mode for beginner

what would be the easiest way to get a 5point star on the screen, i have tried some mathematical equaions but i can seem to get it right. Anyone know a good way???

Start with a 10 vertex circle, then scale every other vertex towards the middle. Use a trifan with an extra starting point in the middle to start with and it will appear correctly without additional subdivision, remember to duplicate the second vertex at the end to complete the shape.

thanks, i’ll give it a show

i got the star! now is there a way to fill in the color within the star???
