What happens if you connect 6 equilateral triangles at each vertex? You get a flat surface known as regular triangular tiling. The shape is now two dimensional, and it can spread out infinitely in ...

In two dimensions, it’s the Reuleaux triangle: an equilateral triangle with curved arcs connecting each corner, creating a shape with a constant width but a smaller area than a circle.

Many are shaped differently based on how acute or obtuse the angles on each point are. The type of triangles definitely matters when understanding the symbolism. An equilateral triangle ...

This shape, with rounded corners ... It’s possible to construct a curve of constant width not only from an equilateral triangle but also from any polygon with an odd number of sides.

Interior angles are the angles that are created inside a shape where the sides meet. The interior angles in a triangle always add up to 180º. An equilateral triangle has 3 sides of equal length.

The majority of the objects turned out to have an equilateral-triangle shape (Supplementary Fig. S7), allowing us to assume that the actual RNP architectures were close to the designed ones.

This process of transforming one shape into another by cutting the ... we have finally solved Dudeney's puzzle by proving that the equilateral triangle and square have no common dissection with ...

A pyramid is named by the shape of its ‘base’. A pyramid with a triangular base is a triangle-based pyramid. A tetrahedron is a triangular pyramid with all equilateral triangle faces.
