Question

quadrilateral abcd is a square. which of the following is true about abcd? it has four right angles. diagonals bisect opposite angles. all of these are true. diagonals are perpendicular.

Explanation:

Step1: Properties of a square

A square is a quadrilateral with four equal sides and four right angles.

Step2: Diagonals of a square

The diagonals of a square are perpendicular to each other (\(90^{\circ}\) angle between them). Also, the diagonals bisect the opposite angles (divide them into two equal angles of \(45^{\circ}\) each as each angle of a square is \(90^{\circ}\)).

Answer:

C. All of these are true.
