## What is the only quadrilateral that is not a parallelogram?

## What is the only quadrilateral that is not a parallelogram?

An ordinary quadrilateral with no equal sides is not a parallelogram. A kite has no parallel lines at all. A trapezium and and an isosceles trapezium have one pair of opposite sides parallel. A Concave quadrilateral or arrowhead does not have parallel sides.

## What quadrangle has two pairs of equal sides but is not a parallelogram?

kite

A trapezoid, in which the non-parallel sides are equal in length, is called isosceles. A quadrilateral with two separate pairs of equal adjacent sides is commonly called a kite.

**Which is not a parallelogram * 1 point?**

Hence, the answer is Trapezium.

### Which is a trapezoid but not a parallelogram?

A trapezoid has one pair of parallel sides and a parallelogram has two pairs of parallel sides. So a parallelogram is also a trapezoid. Carlos says, No – a trapezoid can have only one pair of parallel sides.

### What is a quadrilateral but not trapezoid or parallelogram?

Explanation: Kite: two pairs of adjacent sides are of equal length. This implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. It also implies that the diagonals are perpendicular.

**Is a trapezoid a parallelogram?**

A trapezoid can be called a parallelogram when it has more than one pair of parallel sides.

#### What shape is a rectangle but not a parallelogram?

A rectangle also has the special characteristic that all of its angles are right angles; all four of its angles are congruent. The other special case of a parallelogram is a special type of rectangle, a square.

#### Which figures can have two sides of the same length but are not parallelograms?

Some define a trapezoid as a quadrilateral having only one pair of parallel sides (the exclusive definition), thereby excluding parallelograms. Others define a trapezoid as a quadrilateral with at least one pair of parallel sides (the inclusive definition), making the parallelogram a special type of trapezoid.

**What are not parallelograms?**

A trapezium is the quadrilateral that is not a parallelogram as its two sides are not parallel.

## Which of these is not a parallelogram?

Among the given options , trapezium is not a parallelogram. A parallelogram is a quadrilateral with 2 pairs of opposite, equal and parallel sides.

## Is a trapezium a parallelogram?

All trapeziums are parallelograms, but all parallelograms are not trapeziums.

**Is a rhombus a parallelogram yes or no?**

Is every rhombus a parallelogram? Yes. A parallelogram is a quadrilateral with 2 pairs of parallel sides. The opposite sides on every rhombus are parallel, so every rhombus is a parallelogram.

### Is rhombus a parallelogram?

Definition of Rhombus and Parallelogram The opposite angles are equal. However, if all the angles of a rhombus are 90 degrees then the rhombus is termed as a square. Also, every rhombus is considered as a parallelogram but the converse is always not true. Parallelogram: A parallelogram is a flat-shaped figure.

### Is rhombus a parallelogram or not?

The diagonals of the rhombus meet each other at the right angle and form a scalene triangle. The opposite angles are equal. However, if all the angles of a rhombus are 90 degrees then the rhombus is termed as a square. Also, every rhombus is considered as a parallelogram but the converse is always not true.

**What shape has 4 sides but none of them are the same length?**

Quadrilaterals are polygons with four sides (hence the beginning “quad”, which means “four”). A polygon with non-equal sides is called irregular, so the figure that you are describing is an irregular quadrilateral. This figure has side lengths of 1, 2, 3, and 4 respectively, so it is an irregular quadrilateral.

#### What do you call a four-sided shape with unequal sides?

A scalene quadrilateral is a four-sided polygon that has no congruent sides. Three examples are shown below.

#### Which of the following figure is not a special parallelogram?

So, from the above definitions it is clear that trapezium is not a parallelogram, as for being a parallelogram each pair of opposite sides must be equal and parallel. Hence, the answer to the above question is option (c).

**What is a non parallelogram?**

If the four sides do not connect at their endpoints, you do not have a closed shape; no parallelogram! If one side is longer than its opposite side, you do not have parallel sides; no parallelogram! If only one set of opposite sides are congruent, you do not have a parallelogram, you have a trapezoid.
