By drawing in the equilateral. triangle formed by the circles’ centers and adding a large. circle centered on this triangle, he found and proved. Theorem I: The ratio of the diameter of the ...

Our series reveals the math hidden in familiar places. How much do you know about taxicab geometry, triangular numbers, the ...

A peer-reviewed study in the Journal of Mathematics and the Arts reported that an equilateral triangle traced from the navel ...

THE principal novelties in this tract are the chapters on the orthopole (with some original propositions by the author) and on orthogonal projection (mostly after Prof. Neuberg). A pretty theorem ...

In mathematical terms, a symmetry is something you can do to a system that leaves it unchanged. Consider the act of rotation. If you start with an equilateral triangle, you’ll find that you can rotate ...

The reason the shape changes from 3D to 2D when you get to six triangles has to do with the number of degrees in an equilateral triangle. There are 60 degrees at each vertex of the triangle, so ...
