On a sphere you can draw a triangle with three right angles. . At the North pole , zero meridian and its right angle 90 oW merdian. Draw these meridians to the Equator, and you will find they both meet the Equator at 90 o (degrees).
Quadrilaterals in general have four sides and four angles. Rhombuses, trapezoids, parallelograms, squares, rectangles, and other similar shapes are included among these.

There are infinitely many quadrangles - all of which are polygons - that have sides of different length and angles that are not right angles. There is, however, no specific name for such quadrangles because there are so many different possible shapes.
No
Regular shapes:all sides and angles are the same Irregular shapes: different angle and sides
Squares and rectangles.

A shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
rectangle
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.

There is no shape with exactly 4 right angles and 2 congruent sides.A rectangle has 4 right angles and 2 pairs of congruent sides - 4 sides in all. But if the numbers in the question are not limiting, then there are many more shapes. An irregular hexagon with the following shape, will meet the requirements if its height is the same as its base.___|....\|......\___!_______|There are lots more shapes with more sides.
No, only squares and rectangles have four sides and four right angles (90 degrees). Parallelograms, trapeziums, kites, and rhombuses all have four sides, but they have different size angles.
