Steps

  1. draw a circle d with centre at C and radius CB
  2. construct the image of the circle c through the circular inversion over the circle d
  3. draw a line f which is tangent to c' and passes through B
  4. represent the line f in circular inversion through the circle d, resulting in a circle f which is the solution to the problem

Steps

  1. draw a line p1 passing through points B and C
  2. draw the axis p2 of line BC
  3. draw the line p3 passing through points A and B
  4. at the intersection of the lines p2 and p3 there is a point S1, which is the centre of the circle k1
  5. draw the circle k1 with radius S1B, which is the solution of the problem
