In geometry, the spiral of Theodorus (also called square root spiral, Einstein spiral or Pythagorean spiral) is a spiral composed of right triangles, placed edge-to-edge. It was named after Theodorus of Cyrene. Which triangle has an area of 1?
Triangle 4
Triangle 1 hypotenuse =sqrt (2)
Triangle 2 hypotenuse = sqrt (3)
Triangle 3 hypotenuse = sqrt (4) = 2
Area of triangle 4 = (1/2) * ( hypotenuse of Triangle 3) * ( 1 ) = (1/2) * 2 * 1 = 1
