Then ABD is a 30°–60°–90° triangle with hypotenuse of length 2, and base BD of length 1. The fact that the remaining leg AD has length √ 3 follows immediately from the Pythagorean theorem. The 30°–60°–90° triangle is the only right triangle whose angles are in an arithmetic progression.
30–60–90 triangle. In recreational mathematics, a polydrafter is a polyform with a 30°–60°–90° right triangle as the base form. This triangle is also called a drafting triangle, hence the name. [1]
A black square represents the borders of the file. Inside, the triangle is depicted with all of its special angles. The right angle is symbolized by a small square, and its measure, 90°, is written to the right and above it. The angle placed to the right of the 90° angle is shown as an arc, and its measure, 30°, is written to the left of the ...
A 30°–60°–90° triangle has sides of length 1, 2, and . When two such triangles are placed in the positions shown in the illustration, the smallest rectangle that can enclose them has width 1 + 3 {\displaystyle 1+{\sqrt {3}}} and height 3 {\displaystyle {\sqrt {3}}} .

It is constructed by congruent 30-60-90 triangles with 4, 6, and 12 triangles meeting at each vertex. Subdividing the faces of these tilings creates the kisrhombille tiling. (Compare the disdyakis hexa- , dodeca- and triacontahedron , three Catalan solids similar to this tiling.)
