Yes.
You have to specifically give the problem with the dots, but it can form all equilateral triangles.. .. . .. . . .
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.

A parallelogram.
Join the 6 triangles like pizza slices
Equilateral triangles are also equiangular.

Any n-sided regular polygon, by joining a single vertex up to each of the others, will have a total of (n - 2) triangles inside. In this case, an 11-sided polygon will contain 11 - 2 = 9 triangles.
draw a big triangle then make a line halfway through it
the sum of the angles of a plane triangle is always 180° In an equilateral triangle, each of the angles is = Therefore, the angles of an equilateral triangle are 60°
Using Pythagoras' theorem it is impossible for an equilateral triangle with equal sides of 10 inches to have a height of 7 inches.
