For future reference...Kaye England has created Quarter Square and Half Square Triangle rulers that I really like. Her math is easy to calculate to get the size triangle you want. The triangles are cut from strips of fabric.
Her line of rulers are called "Nifty Notions". The colors on her rulers are pink for 1/4" and green for 1/2". I find these easier to read than the all yellow ones.
For cutting the strips DH and I like the Tru Cut ruler and companion rotary cutter made by the Grace company for more accurate strips. Happy Sewing!
