a square or a rectangle
A quadrilateral with all right angles is a rectangle.
None of the angles between edges are greater than 90o - they are all 90o as each face is a square with a right angle at each corner, and each face is at right angles to the faces to which it is joined.
the angle is an angle and therefore doesn't have a length. If you want to find the length of the hypotenuse - the leg across from the right angle - it is the square-root of the other two legs each squared.
A right angle is 90 degrees. If you split it in half perfectly, each resulant angle would then be 45 degrees. (90/2). Source- 12 years of math.
