A square.
A rhombus is never a rectangle. A rhombus has four sides that are equilateral whereas with a rectangle the two sides are equilateral and the two ends are equilateral.
Not necissarily. Quadrilateral simply says it has 4 sides. A rectangle has perpendicular sides. Equilateral means that the sides are of equal length (like a square, which is a special case rectangle)
"equilateral" is a fancy word meaning "has all sides equal". Such a rectangle is called a square.
no, equilateral means that all sides are the same length, Squares, which are rectangles, are equilateral.
A rectangle is not always equilateral. A square and a rhombus both have four equal sides.
A rectangle by definition has four right angles, so it cannot be equilateral. An equilateral shape has all sides of equal length, which would make it a square or rhombus, but not a rectangle.
It's a square. A rectangle is any polygon with two pairs pf parallel sides all intersecting at perpendicular angles. It's diagonals are also congruent. This is also true with a square. So, a square could also be considered a rectangle. The only difference is that a square's sides all have to be the same length, and a rectangle's doesn't. 'Equilateral' means all the sides are equal. Therefore, an equilateral rectangle is a square.
A square has all four equilateral sides, whereas a rectangle has two sets opposite sides that are congruent. A rectangle can be a square, but a square can not be a rectangle.
Only if all the faces (sides) are the same length. A rhombus is the equilateral version of a parallelogram, just like a square is the equilateral version of a rectangle.
A quadrilateral has four sides, and the fact that it is equilateral means the sides all have the same length, so the only possible shapes with four sides of equal length are a square and a rhombus.
A square and rectangle all fit this description.
The rectangle which is equilateral is called as square.
