1. All four angles of a quadrilateral can be acute.
Give a reason to support your answer.
2. Can a quadrilateral have all its interior angles equal to right angle?
Give a reason to support your answer.
Answer variants:
If each angle is a right angle, then the total will be \(360^\circ\) which satisfies the angle sum property of a quadrilateral.
If all four angles were acute, each would be less than \(90^\circ\). Then, their total would be less than \(360^\circ\)
No, all the angles of a quadrilateral cannot be right angles because the sum of the angles would be more than \(360^\circ\)
Because all are obtuse angles
