If All of the following hold: (1) equal X and secant line (2) Y is a vertex of X (3) Z is a vertex of X (4) equal Y and Z (5) equal W and circle (6) Y is a vertex of W (7) Z is a vertex of W, then there exists V such that equal V, chord of a circle, Y, Z are endPointsOfLine of V, and X is a geometric part of V |
