Answer:  Yes

Solution.


Right angle is an angle equal to 90^{\circ}
Let all angles of a quadrilateral be right angles. 
Hence sum of all angles = 90^{\circ} + 90^{\circ} + 90^{\circ} + 90^{\circ} = 360^{\circ}
So we can conclude that, if all the angles are equal to 90^{\circ} then the sum of all the angles will be equal to 360^{\circ}
Also, we know that sum of all the angles in a quadrilateral is 360^{\circ}.
Therefore, a quadrilateral can have all angles as right angles.
Hence given statement is True.
