Yes.
Since any polygon can be constructed from a combination of other polygons, I would call this rule a "trivial property of polygons".
You have to specifically give the problem with the dots, but it can form all equilateral triangles.. .. . .. . . .
Rohmbus is a four sided figure (quadrilateral) that is made up of two equilateral triangles

A parallelogram.
Join the 6 triangles like pizza slices

Equilateral triangles are also equiangular.

Regular tessellations can be made using triangles, squares, and hexagons.
Because all other polygons are made from triangles as for example an 8 sided octagon has 6 triangles within it or a 6 sided hexagon has 4 triangles within it.
Cross two match sticks to bisect like X and place the other two match sticks at the base of the two equilateral triangles formed .
Construct/make a tetrahedron, which is three-dimensional.
