the incentres of the four triangles determined by the vertices of a cyclic quadrilateral taken three at a time form a rectangle. The British flag theorem...

{\displaystyle B.} Every right triangle is half of a rectangle which has been divided along its diagonal. When the rectangle is a square, its right-triangular...

so this triangle forms half of a golden rectangle. The convex hull of two opposite edges of a regular icosahedron forms a golden rectangle. The twelve...

A love triangle is a scenario or circumstance, usually depicted as a rivalry, in which two people are pursuing or involved in a romantic relationship with...

adjoining right triangles, tracing a whirl of converging silver rectangles. The logarithmic spiral through the vertices of adjacent triangles has polar slope...

the right angled triangle is the diameter of its circumcircle. The formulation in terms of areas yields a method to square a rectangle with ruler and compass...

these three lengths form the sides of a right triangle. The same triangle forms half of a golden rectangle. It may also be found within a regular icosahedron...

sides have length zero, the rectangle degenerates to a point. A hyperrectangle is the n-dimensional analog of a rectangle. If its sides along any of the...
