Determine if each statement is true if
(i) PQRS is a rectangle
(ii) PQRS is a square
In each case, if true, explain why.
(a) PQ = SR
(b) PT =TR
(c) ST = RT
(d) PS = ST
(a) True for both rectangles and squares; opposite sides are congruent.
(b) True for all parallelograms, so true for both rectangles and squares; diagonals bisect each other.
(c) True for squares, diagonals are the same length, so are of the diagonal.
(d) False
