      From the geometry one sees that the first right triangle has angles of π/4, π/2, and π/4 when expressed in radians. Also by the Pythagorean theorem one finds the hypotenuse of the first triangle to be 1/sqrt(2). The second right triangle shown has the angles π/6, π/2, and π/3 with a hypotenuse of length 1.
