## Can a parallelogram have exactly 3 right angles?

Quadrilaterals have 4 sides and 4 angles. The exterior angles of any convex polygon (ie no interior angle is less than 180 degrees) add up to 360 degrees ( 4 right angles). … Therefore, if 3 internal angles are right angles, the 4th angle must also be a right angle. So no quadrilaterals have exactly 3 right angles.
