Secant line point a "tangent line" and in no points an "exterior line". A "chord" of a circle is the line segment that joins two distinct points of the circle. A chord is therefore contained in a unique secant line and each secant line determines a unique chord. In rigorous modern treatments of plane geometry, results that seem obvious and were assumed (without statement) by Euclid in his treatment, are usually proved. For instance, "Theorem (Elementary Circular Continuity)": If formula_1 is a circle and formula_2 a line that contains a point that is inside formula_1 and a point that is outside of
Circle of Two like Laurence Olivier, for his willingness to do anything for money. He stooped so low in 1981 as to appear in Jules Dassin’s "Circle of Two", in which he plays a 60-year-old artist who falls for the 16-year-old Tatum O’Neal.
