Voila!! Two HSTs, no bias edges!!!!
I always make mine a little larger and then trip to size using the sewn seam to square up with. That way they are precise .... and give me the accuracy when joining them into blocks!!
If you need multiples ..... just draw the required number of squares on a larger piece of fabric. Add the diagonals. Stitch and then cut on the grid lines as well as the diagonals. Then square and trim.
Easy peasy for a multitude of HSTs in no time!
This is the way I do as well. If I have a lot of them I have the software Trianglations 2 and also 3; (3 includes the 16th measurments as well as a new way to do flying geese). You use the cheap paper from the $ store and print your own; as many or as few as you want.
