Behind the Design

Triangle rulers are a standard school supply, but aligning two of them correctly to draw parallel or perpendicular lines is a stumbling block for younger students. Sonic addressed this by color-coding each side of both rulers, so the instruction becomes simple: match the colors.

The other key detail is that every edge carries a measurement scale. Most triangle rulers only mark certain sides, which forces students to rotate or flip to find a usable edge. Here, any side placed against paper is also a ruler, reducing the handling needed mid-task.

A color-coded triangle ruler set designed for classroom use, where each side is a different color so students can align them to draw perpendicular and parallel lines without confusion. Every edge has markings, so you can measure from any side without flipping or guessing.
