About the Triangle Ruler Set Square black filled icon
A right-angled triangle ruler standing on its vertical edge, with numbered graduations running up the left side and along the bottom edge, and a smaller triangular cutout in the middle that leaves the tool as a frame. It communicates geometry, measurement, drafting and technical drawing. Use it in education apps, math lesson materials, design tool palettes, engineering documents and stationery shop categories.
The outer hypotenuse runs from the tall left corner down to the bottom-right, and the inner cutout repeats that angle at reduced scale, which keeps the shape open and light. Tick marks of alternating length imitate a real scale. It sits beside protractor, compass and pencil icons in a drafting set; at 16px drop the numerals and keep only the ticks.
This is the solid black filled version of the triangle ruler set square icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
