Question

What property of a rectangle do we use if we need to construct a rectangle whose adjacent sides are given?

• A. Diagonals are equal.
• B. Each angle of a rectangle is ${90}^{\circ }.$
• C. Diagonals bisect each other.
• D. Diagonals bisect each other at ${90}^{\circ }.$

Answer 1

The correct option is B

Each angle of a rectangle is ${90}^{\circ }.$

To construct a rectangle given its adjacent sides, we need to know the included angle.

Thus, we use the property each angle of a rectangle is ${90}^{\circ }$. By knowing this we can have the measure of all sides and angles of a rectangle. Hence, it's possible to construct an unique rectangle.
