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.
Yes, a trapezoid can have 3 right angles.
12 right angles.
3 right angles.
no. if you have 3 right angles it is impossible to not have a 4th right angle which would then be a square
a tetrahedron has 3 Right angles

A pentagon with 3 right angles is considered to be an irregular pentagon because not all angles and all sides are equal.
3 right angles

There are 3 right angles in the letter F

If the question is about a plane shape with exactly 3 right angles it could be an irregular polygon of 5 or more sides. If the shape can have more than 3 right angles then a square or rectangle are also possible. Finally, in 3 or more dimensions, a polyhedron with any number of faces can have 3 or more right angles.
