Which is always a rhombus? Parallelogram, Trapezoid, Rectangle, or square?

Question

Which is always a rhombus? Parallelogram, Trapezoid, Rectangle, or square?

Answer 1

Parallelogram

Answer 2

Actually it's a square. Since a rhombus needs to have 4 equal sides, only a square can ALWAYS be a rhombus.

Answer 3

A rhombus is a figure with four equal sides. A square is just a special case of rhombus in which all the four angles are equal to 90 degrees. Thus, a square is always a rhombus.

Answer 4

A rhombus is a special case of a parallelogram of which all sides have equal length.

Hence, any parallelogram may not be a rhombus. Trapezoid and rectangle are definitely not.

A square is a special case of a rhombus of which all angles are the same (90 degrees).

Answer 5

A rhombus is a parallelogram with four equal sides.

A square is a polygon with 4 equal sides & 4 90* angles.

Therefore, all squares are rhombuses, but not all rhombuses are squares.

Answer 6

In a rhombus, opposite sides are parallel. One analogy holds that the rhombus is to the parallelogram as the square is to the rectangle. In its turn, the square is a special case of the rhombus, being most readily defined as a rhombus with one right angle.

So answer should be a SQUARE

Answer 7

square. A rhombus always has 4 equal sides and so does a square.

Answer 8

The answer to this question is: the square. It is always a parallelogram because it's sides are parallel and they are equal. So that makes a rhombus... no matter how big the square is. :)

Answer 9

square

a rhombus has to have 4 = sides, the opposite sides are parallel

Answer 10

The definition of a rhombus is a parallelogram with all sides congruent. A parallelogram is not always a rhombus, but a rhombus is always a parallelogram. The definition of a square is a parallelogram with all right angles and all sides congruent. Thus, a square is always a rhombus.

ANSWER: Square

Answer 11

A square (sorry, i correct myself here.)

4 sides, 2 pairs of identical angles (all the angles are equal!), equal side lengths.

Answer 12

To be a rhombus, you need four equal sides.  Only a square ALWAYS has four equal sides.

Answer 13

A rhombus is a special kind of parallelogram.

It is a parallelogram with 4 equal sides.

Diagonals bisect each other at 90°

It is a square

Answer 14

A rhombus is defined as a polygon with 4 equal sides.  A square is the only item that always fits this description.  A square is just a rhombus with a 90-degree angle.

Answer 15

square
