A rectangle has 4 right angles
A rectangle has 4 right angles
It does not exist as a 5 sided polygon. To have 5 sides, it must have 5 angles (or vertices). The sum of the angles of a 5 sided polygon is (5-2) x 180o = 540o. The sum of 4 right angles is 4 x 90o = 360o → the 5th angle is 540o - 360o = 180o which is a straight line There are infinitely many points with such an angle along each of the sides; or to put it another way, for a vertex to exist it cannot have an angle of 180o. Thus if the polygon has 4 right angles, it cannot be a 5 sided polygon.

4 right angles, by definition, are four angles of the same measure, and therefore must be congruent angles.
A rectangle.
A square.
A square
A trapezium has 4 right angles...Correction: it has 4 angles but they are not right angles. A structure/shape with 4 right angles is a rectangle or square.
2 pair = 4, so 4 right angles is a rectangle. A square is a special case of rectangle.
rhombus
Yes a square always has 4 right angles but a rhombus never has any right angles.
