  2. Special right triangle - Wikipedia

    en.wikipedia.org/wiki/Special_right_triangle

    Set square, shaped as 30° - 60° - 90°° triangle The side lengths of a 30°–60°–90° triangle 30° - 60° - 90° right triangle of hypotenuse length 1. This is a triangle whose three angles are in the ratio 1 : 2 : 3 and respectively measure 30° (⁠ π / 6 ⁠), 60° (⁠ π / 3 ⁠), and 90° (⁠ π / 2 ⁠).

  3. Rep-tile - Wikipedia

    en.wikipedia.org/wiki/Rep-tile

    A right triangle is a triangle containing one right angle of 90°. Two particular forms of right triangle have attracted the attention of rep-tile researchers, the 45°-90°-45° triangle and the 30°-60°-90° triangle.

  5. Set square - Wikipedia

    en.wikipedia.org/wiki/Set_square

    These set squares come in two usual forms, both right triangles: one with 90-45-45 degree angles, the other with 30-60-90 degree angles. Combining the two forms by placing the hypotenuses together will also yield 15° and 75° angles.

    en.wikipedia.org/wiki/Ailles_rectangle

    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}}} .

    en.wikipedia.org/wiki/Polydrafter

    306090 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]

  9. Truncated trihexagonal tiling - Wikipedia

    en.wikipedia.org/wiki/Truncated_trihexagonal_tiling

    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.)
