Here is a puzzle for you to try: Name three special properties of an

equilateral triangle to do with its sides, angles and symmetry.

In the case of

equilateral triangle we shall obtain 2[alpha] + [beta] = 3.

I again appreciated the strength of this third side of the

equilateral triangle.

The Philippine flag has two horizontal bands of blue and red with a white

equilateral triangle based at the hoist side and a golden yellow sun in the centre of the triangle with eight primary rays - each containing three individual rays.

The church has tried to explain the Trinity by using all kinds of natural analogies: a tree with roots, trunk, and branches; the sun with its light, heat, and rays; water which may be liquid, ice, or gas; an

equilateral triangle with three equal angles and sides; or even an egg with a shell, yoke, and egg-white.

The directed edge-labeled triangular graph in Figure 16 is built as follows: first form a dense triangular vertex grid of

equilateral triangle vertices (shown inside the triangle [DELTA]abc in Figure 16.

The piston has an

equilateral triangle shape with curved sides.

The intersection of motor arms is out of question due the fact that their length H is less then the radius R of the circle inscribed in the

equilateral triangle of the base.

Other theories suggest the Babylonians based their number system on the division of the circle into 360 units, or from the 60 degree angle of the

equilateral triangle.

In this work, a solution to measure a teacher's views toward such a triple is offered by way of a three-way slider embedded in an

equilateral triangle.

For any triangle with interior angles [alpha], [beta] and [gamma], one has that f([alpha]) = f([beta]) = f([gamma]) = k which are the lengths of the sides of an

equilateral triangle with sides of length k.

Attention will be restricted to this case as it is the one most relevant to the extension of the results for the eigenstructure of the

equilateral triangle [4, 5] from real to complex values of [sigma] which furnishes the motivation for the present one-dimensional study.
