Two circles with radius 1 are externally tangent at B, and have AB and BC as diameters. A tangent to the circle with diameter BC passes through A, and a tangent to the circle with diameter AB passes through C so that the tangent lines are parallel. Find the distance between the two tangent lines.

You can use coordinates, to get the disantce between the lines is 3/2.
