| If we draw out from the center of the circle to the base of this triangle a vertical line, then the two angles formed on both sides of this vertical line will be right-angled, and the [original] triangle, due to this drawn out vertical line, will be halved into two right-angled triangles, and the two lines falling on the two extremities [of the locus of contact] will become hypotenuses of these two right-angled triangles, and the vertical line becomes a hypotenuse of [i. That is, the sum of the two hypotenuses represented the length of the cable. |
