Quadrilaterals are polygons having four sides. Quadrilaterals may have 1, 2, or 4 right angles. It is impossible for a quadrilateral to have exactly 3 right angles because the fourth angle would also be a right angle.

Can a parallelogram have 3 right angles?

Depends on your question. A rectangle is a parallelogram and has 4 right angles. BUT A parallelogram can have only a total of one, two, or four right angles. Mathematically, 3 right angles is 270 degrees. A parallelogram has 360 degrees. 360 - 270 = 90 degrees = right angle.

How do you draw 3 lines and get 4 acute angles 4 right angles and 4 obtuse angles?

Extend all the lines of a right-angled triangle with sides of 3, 4 and 5 units. The extension of the lines forming the right angle will produce 3 other right angles. The extension of the lines forming the other two angles will produce 6 other angles. This gives a total of 12 angles, 4 of which are acute, 4 right and 4 obtuse.
