Using such an equilateral triangle in the Vitruvian Man drawing helps produce a specific ratio – 1.64 – between the size of the square and the circle in the artwork.

I was particularly fascinated by how the 10 pins were placed at the start of each frame, neatly arranged in an equilateral triangle with rows of one, two, three and four pins. Ten is called a ...

Discusses the properties and types of triangles, explaining that a triangle is a closed figure with three sides and angles. It categorizes triangles into equilateral, isosceles, scalene, obtuse ...

This large, nearly equilateral triangle is composed of three of the brightest stars in the sky, each belonging to its own constellation.

Our physics expert picks his top-five equations, plus a scheme to supply US power needs with a bucket of baseballs. Thanks, Einstein!

Here’s how he drew this picture. First he drew a lattice of equilateral triangles on the plane. Then he drew an 11-sided polygon whose corners are lattice points. Along each edge of this polygon, he ...

So equilateral triangles are constructible with a compass and straightedge, QED. Congratulations on persisting through the first proposition in the first book of Euclid’s Elements.

To represent this in two dimensions, again draw an equilateral triangle, followed by a circle centered around one of the triangle’s vertices, with a radius as long as each of the triangle’s legs.

If you average out the number of building permits in the past 17 years in the Raleigh-Cary metro, that comes to about 12,500 single-family units a year. So to argue that homebuilders are applying ...

Spread the loveAn equilateral triangle is a type of polygon with three congruent sides and angles, each measuring 60 degrees. This simple yet elegant geometric shape has various applications in art, ...
