This multi-sized ruler features two triangles in one!

Use the 45 degree side to cut half-square triangles from strips up to 5.5″ wide, creating half-square triangles up to a finished size of 5″.

Or use the 90 degree side to cut quarter triangles that finish up to a 5″ finished quarter-square triangle. The math required to cut these angles is incorporated into the easy to read black and white markings, making your next project a breeze!
