A Rhombus.
rhombus. The rhombus is a quadrilateral with all sides equal in length. It is also a parallelogram, so opposite sides are parallel and equal in length, and opposite angles are equal.
Quadrilateral
quadrilateral means having all sides the same length. when you make a shape with 3 obtuse angles and with the same length on the sides, only 3 of them will have the same length which is the sides of the 3 obtuse angles. then the last side will be too long. obviously it is no more quadrilateral.
A quadrilateral with 4 right angles and opposite sides that are parallel can be either a rectangle if the adjacent sides are of different length or a square if the adjacent sides are of the same length.
Square
a pentagon
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.
A square. Four 90 degree angles allow a quadrilateral to have equal sides.
a squareThe only quadrilateral that has two pairs of sides the same length and all angles equal is the square.* * * * *The correct answer is a rectangle.
If both pairs of opposite sides are the same length, and both pairs of opposite angles are the same, the quadrilateral is a parallelogram (rhombus, rectangle, or square).
