Problem 2

This figure contains 2 parallel lines and a point. Construct all circles that pass through the point and that are also tangent to the two lines.

Problem 3

This figure contains 2 parallel lines and a point on one line. Construct all circles that pass through the point and that are also tangent to the two lines.

Problem 4
