After cutting the half-square triangles rotate the Cutting Guide to the opposite 45° angle.

To cut half-rectangle triangles, follow the steps for cutting  half-square triangles except the angle you set will not be 45°. The  angle you need will depend on the width and length of your rectangle.

To cut equilateral triangles, rotate the Cutting Guide to the left 60° angle, cut, then move it to the opposite 60° angle.
