Lydian uniquely features a quotation mark in the shape of a right triangle. Later, they came to mean a right triangle. The legs of a right triangle are perpendicular to each other. The result is a right triangle with . Each right triangle is a fundamental domain. If the catheti of a right triangle have equal lengths, the triangle is isosceles. This result is known as Fermat's right triangle theorem. Each of these triples gives the integer sides of a right triangle. Then , so these three lengths form the sides of a right triangle. Pack "n" unit circles into the smallest possible isosceles right triangle. In the figure, consider the right triangle .
