You can place one circle on the y-axis, copy it to the next tick and rotate that one by 144°
Then copy both of these circles onto the next 2 snaps and rotate them by 288°
Then copy the y-axis symmetric circle (here the bottom right one) to the last snap and Ctrl+H. Done. But if you ask me, create polygons is more convenient, because you don't have to remember a set of numbers and there is no danger of accidently deleting notes by scrolling to the wrong tick for pasting etc.
