Put this page to work.
Connect adjacent points to create triangles, diamonds, or hexagons. Each triangle has three equal edges, so repeating steps preserve a consistent scale.
The measurement to know: equilateral-triangle edge length. Row height equals the chosen edge length × √3 ÷ 2. Alternating rows are offset by half an edge to make the triangular lattice.
On this sheet: triangle edge: 12 mm; row height: 10.39 mm; dots: 190. The drawing area is 119.7 × 195.9 mm.
