A parallelogram whose sides are equal in length is always a rhombus. In addition, it may be a rectangle. If it's a rectangle, then it's also a square.
A Rectangle
If a rectangle has its length equal to its width, then all four sides are of equal length and it is a square.
When all sides are equal it has a to be SQUARE. Which is the only shape that is a regular quadrilateral.
A rectangle must have two pairs of equal sides. So to find the area of a rectangle, the rule is just length x width.8x9 = 72cm^2
A square
There is no way to know.If two opposite sides are parallel and of equal length, then the quadrilateral is a parallelogram (rectangle, rhomboid, square, or rhombus).
A square and a rectangle are both quadrilaterals, all of whose vertices are right angles. A rectangle has two pair of sides of equal length with one pair being different from the other. A square has all four sides equal.
It can be, but it has to pass an extra test. A square is one particular kindof rectangle ... it's a rectangle whose length and width are equal.If a rectangle's length is not the same as its width, then it's not a square.======================================================absolutelly right, and you said it better than I did.I said:because a square has 4 equal sides and a rectangle has two equal sides parallel and two more parallel and equal sides.
A parallelogram.Types of parallelogram:Rhomboid - A quadrilateral whose opposite sides are parallel and adjacent sides are unequal, and whose angles are not right anglesRectangle - A parallelogram with four angles of equal sizeRhombus - A parallelogram with four sides of equal length.Square - A parallelogram with four sides of equal length and four angles of equal size (right angles).
A square is a rectangle whose adjacent sides are equal.
A square is a rectangle whose adjacent sides are equal.
