Answer 1

Answer:

See explanation

Step-by-step explanation:

Definitions of parallelogram and rectangle:

A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel.

A rectangle is a parallelogram with four right angles.

This gives us that each rectangle is a parallelogram.

But an arbitrary parallelogram can have angles that are not necessarily right (for example, 60°, 120°, 60°, 120°). Thus, there are a lot of parallelograms that are not rectangles.
