WebThe diagonals of a parallelogram bisect each other. If one pair of opposite sides is equal and parallel in a quadrilateral then it is a parallelogram. Theorem 1: In a Parallelogram the Opposite Sides are Equal. Proof: … Cantor considered the set T of all infinite sequences of binary digits (i.e. each digit is zero or one). He begins with a constructive proof of the following lemma: If s1, s2, ... , sn, ... is any enumeration of elements from T, then an element s of T can be constructed that doesn't correspond to any sn in the enumeration. The proof starts with an enumeration of elements from T, for example
