Triangle template — printable equilateral triangles
Equilateral triangles (all sides equal) in exact sizes — the size is the length of each side.
Printing at the exact size
Each shape is drawn so its widest (or tallest) side is exactly the size you pick. In the print dialog choose “Actual size” or “100%” — not “Fit to page”. Small sizes fill the page with copies; large sizes print one per page. Shapes wider than the paper's printable area (for example an 8-inch circle on A4) print as a left and a right half on two pages: cut the first half along the dashed line, lay it on the dashed line of the second page and tape.
