Do parallelograms have parallel sides?
Yes. A Parallelogram is a quadrilateral that has two pairs of parallel sides which are opposite each other and of equal length, though the pairs may be of different length to each other. If the angles are all 90° then the parallelogram is also a rectangle. If the angles are all 90° AND all sides are equal then the parallelogram is also a square. All squares are rectangles, but not all rectangles are squares; Similarly all squares are rhombuses but not all rhombuses are squares And all rhombuses, and thus squares, are parallelograms, but not all parallelograms are rhombuses (nor squares).
Can a quadrilateral be a parallelogram and a rhombus?
Yes. All rhombuses are parallelograms, but the reverse is not true. (I.e. there are parallelograms which are rhombuses and there a parallelograms that are not rhombuses. -- Just like Every bus has wheels but not everything with wheels is a bus.)
Is it true that rhombuses are special parallelograms?
Yes, it is true that rhombuses are special types of parallelograms. A rhombus is defined as a parallelogram in which all four sides are of equal length. This means that while all rhombuses are parallelograms, not all parallelograms are rhombuses, as parallelograms can have sides of different lengths. Additionally, rhombuses have the property of having diagonals that bisect each other at right angles.
Why is a rhombus a rectangle but a rectangle is not a rhombus?
A rhombus is a type of parallelogram where all sides are equal in length, and it can have right angles, which means it can be classified as a rectangle if those right angles are present. However, a rectangle is defined as a parallelogram with right angles but does not require all sides to be equal; therefore, not all rectangles can be rhombuses. Essentially, while all rhombuses can be rectangles when they have right angles, rectangles do not necessarily meet the criteria to be rhombuses.
What is different between a parallelogram and a rhombus?
They are basically the same thing however, a rhombus has the sides all congruent and the parallelogram has the opposite sides congruent. If the rhombus had angles of 90 degrees it would become a square and if a parallelogram had sides 90 degrees it would become a rectangle. All rhombuses are parallelograms, but not all parallelograms are rhombuses. Likewise, using the above example of squares, all squares are rectangles but not all rectangles are squares.
Can some rhombuses be parallelograms?
Some rhombuses can be parallelograms. It all depends on the direction of the sides. A diamond is a rhombus that is not a parallelogram A square is a rhombus that is a parallelogram
Are parallelograms rhombuses?
Some parallelograms are rhombuses, but all rhombuses are parallelograms. A parallelogram is a rhombus if and only if all of it's sides are the same length.
Are all rhombuses parellelograms?
All rhombuses are parallelograms because to be a parallelogram you only have to have four sides and have opposite sides congruent.
Can a rhombus be a parallelogram?
All rhombuses are paralleleograms. Rhombuses are parallelograms in which all four sides are the same length (and the opposite angles are congruent). Squares are rhombuses in which all four angles are right.
Why is a parallelogram is not necessarily a rhombus?
The definition of a parallelogram is that it has four sides, the opposite sides are congruent and parallel, and opposite angles are congruent. This includes rectangles, squares, rhombuses, etc.The definition of a rhombus states that it is a parallelogram, but more specifically that all sides are congruent.So a rhombus is a parallelogram, but not all parallelograms are rhombuses.
Are all angles equal on a parallelogram?
THey can be (as in squares and rectangles) but usually aren't (as in rhombuses.)
Are all the angles equal on a parallelogram?
Not necessarily. Squares, rectangles, yes. Rhombuses, no.
Why can a parallelogram not be described as a rhombus?
Although a rhombus is a parallelogram. not all parallelograms are rhombuses. A parallelogram is any shape with two or more pairs of parallel sides.
Are rhombuses always parallelogram?
Yes.
Can rhombuses be called a parallelogram?
Yes
Are all squaresrhombirectangle a parallelogram?
All squares, rhombuses, rectangles and parallelograms are 4 sided quadrilaterals.
Are all rhombus parallelogram?
No for a parallelogram to be a rhombus it would have to have consecutive sides congruent and the diagonals bisect each other. All squares are rhombuses.
