6-3 Proving That a Quadrilateral is a Parallelogram
... Find values of x and y for which ABCD must be a parallelogram. If the diagonals of quadrilateral ABCD bisect each other, then ABCD is a parallelogram by Theorem 6-5. Write and solve two equations to find values of x and y for which the diagonals bisect each other. ...

A topological property 7? is semiregular provided that a topological space (X, t) has property 7? if and only if (X, ts) has property 7?. QHC and connectedness are semiregular. If t and t' are tw ...
