Final answer:
Yes, the definition of a rectangle is reversible. A rectangle is a parallelogram with 4 right angles.
Step-by-step explanation:
Yes, the definition of a rectangle is reversible. A rectangle is a parallelogram with 4 right angles. This means that if a shape has 4 right angles, it is a rectangle. On the other hand, if a shape is a rectangle, it must have 4 right angles.
To write this as a true biconditional, we can say: A shape is a rectangle if and only if it is a parallelogram with 4 right angles.
