Hi...looking at them they are the same star points that are in the Tennesse Waltz quilt or The "54-40 or Fight" block
You can buy a perspect template for the star from Quilt in a Day ( Eleanor Burns) ....I bought it to make the quilt...haven't made the quilt yet but have made some of the blocks and by using the template they are really easy to do and the points are perfect.
Below is a link with a video to show you how they are done
