A rectangle with four equal sides would not be a rectangle, it would be a square. In a rectangle opposite sides are equal in length and are parallel.
A rectangle having all four sides as an equal single length is a square.
A rectangle!
A rectangle has two pairs of equal sides. In other words, opposite sides of a rectangle are equal in length. This property distinguishes a rectangle from a square, which has all four sides equal in length.
A rectangle is a square when all four of its sides have equal length.
The rectangle
A square is a type of rectangle where all four sides have equal length. A diamond has four sides of equal length but differs from a square in that not all four internal angles are equal. A diamond is neither a rectangle, and hence neither a square.
On a square, all four sides are equal in length. A rectangle only has two sets of equal sides.
A square is a rectangle because the definition of a rectangle is that it has four straight sides and the opposite sides are equal in length. Squares have four straight sides, and their opposite sides match up in length. Therefore, a square is also a rectangle.
All four sides of a square are equal in length. Only the opposite sides of a rectangle are the same length. The adjacent sides are different in length.
A square of course!
If a rectangle has its length equal to its width, then all four sides are of equal length and it is a square.
