Not possible... in order for it to have four right-angles, it would resemble a square or rectangle.
Rhombus has 4 equal sides and no right angles
You don't tell us enough information. In a square, there are four sides and four angles. The sides are all equal and the angles are all right angles. In a rectangle, there are four sides and four angles The opposite sides are equal and the angles are all right angles. There is no other shape in which all angles are right angles.
A square. Its opposite sides are equal and it has 4 right angles.
it has 4 equal sides and no right angles
It's impossible for a quadrilateral to have no equal sides and have right angles.
A quadrilateral with four equal sides but no right angles is a rhombus.
A rhombus has four equal sides but no right angles.
Rectangle
A square has 4 equal sides with 4 right angles.
It is a square that has 4 equal sides and 4 right angles.
Yes because it has four egual right angles if it has four equal sides.
The shape you are looking for is a quadrilateral. If you have a square, all angles MUST be right angles. A parallelogram can also have 4 equal sides in length and parallel sides, but a parallelogram doesn't have right angles.
