Question

A parallelogram which has a line of symmetry is a rectangletrue or false​

Answer 1

Answer: False

Explanation:

If a parallelogram has a line of symmetry through each pair of opposite sides, then we have a rectangle.

But if a parallelogram has a line of symmetry through each pair of opposite vertices, then we have a rhombus.

A square is a combination of both cases above.

The statement "A parallelogram which has a line of symmetry is a rectangle" is sometimes true. Overall its false because it implies that all parallelograms with this property are automatically a rectangle.
