What is a key feature of a rectangle?

It has four equal sides
It has only one right angle
It is a parallelogram with a right angle
It has no parallel sides

The correct answer is: It is a parallelogram with a right angle

A key feature of a rectangle is that it is a special type of parallelogram where each of the angles is a right angle (90 degrees). This characteristic distinguishes rectangles from other types of parallelograms, which may have angles that are not right angles. In addition to having right angles, rectangles also possess parallel sides, which run along the same direction. Each pair of opposite sides is equal in length. This unique combination of being a parallelogram and having right angles defines the rectangle. Other choices don't align with the properties of a rectangle. For example, stating that it has four equal sides corresponds to squares, not rectangles. Claiming it has only one right angle contradicts the definition since rectangles must have four right angles. Lastly, asserting that it has no parallel sides is incorrect, as both pairs of opposing sides in a rectangle are parallel.
