Question

It every parallelogram is rectangle? ​

Answer 1

Answer:

Because a square is a rectangle but a rectangle need not be a square, the most general quadrilateral that fits this description is a rectangle. Theorem 16.5: If the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle.

Answer 2

Because a square is a rectangle but a rectangle need not be a square, the most general quadrilateral that fits this description is a rectangle. Theorem 16.5: If the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle.parallelogram is a quadrilateral with 2 pairs of opposite, equal and parallel sides. A rectangle is a quadrilateral with 2 pairs of opposite, equal and parallel sides BUT ALSO forms right angles between adjacent sides. The same way that not all rectangles are squares, not all parallelograms are rectangles.
