A half-rectangle triangle is a rectangle divided on the diagonal to produce a tall triangle. It has three unequal sides and one 90 degree angle.

Drawing – To draw the shape with seam allowances = finished height + ⁵⁄₈in (1.6cm) and finished width + 1¹⁄₄in (3.2cm). Cut this rectangle once on diagonal to yield two units.

Alternatively, draw a rectangle on paper without seam allowances and mark it into two triangles. Add a ¹⁄₄in (6mm) seam allowance around all three sides of one of the triangles. Cut the fabric to this size.

Cutting – Cut fabric into strips first and then into rectangles of the desired size (as calculated in diagram). Re-position the ruler so the 45 degree line aligns with the edge of the rectangle and cut across the diagonal. Check the diagonal cut is sloping in the direction you require.
