**Trapezium**: A quadrilateral having one pair of opposite sides parallel is called a trapezium. A trapezium is not a type of parallelogram. Square: A square is a quadrilateral with all sides of equal length, all angles as right angles and opposite sides parallel to each other.

## Which one is not a parallelogram?

Finally, **a trapezium** is a quadrilateral with one pair of opposite sides parallel and another pair of opposite sides is non-parallel. 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.

## What is an example of a non parallelogram?

**A trapezoid** has only one pair of opposite sides parallel to each other. Also, a trapezoid doesn't have opposite sides equal to each other. Hence, it is a quadrilateral but not a parallelogram.

## What is not always a parallelogram?

A parallelogram is a quadrilateral with 2 pairs of opposite, equal and parallel sides. A rectangle is a quadrilateral with 2 pairs of opposite, equal and parallel sides BUT ALSO forms right angles between adjacent sides. ... The same way that not all **rectangles** are squares, not all parallelograms are rectangles.

## How do you know if its a parallelogram or not?

**If both pairs of opposite sides of a quadrilateral are parallel**, then it's a parallelogram (reverse of the definition). If both pairs of opposite sides of a quadrilateral are congruent, then it's a parallelogram (converse of a property).

### What makes a parallelogram?

In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are **of equal length** and the opposite angles of a parallelogram are of equal measure.

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

**A square** is also a rectangle because it has two sets of parallel sides and four right angles. A square is also a parallelogram because its opposite sides are parallel.

### What are the real life examples of parallelogram?

- Examples of Parallelogram. Tiles. Buildings. Roofs. Paper. Desks. Erasers. Solar Panels. Striped Pole. Steps of a Stair Case. Design on a Cardigan. Structure on the Fret Board of a Guitar.

### Can a parallelogram have exactly 2 right angles?

A parallelogram is a quadrilateral with 2 pair of opposite sides parallel. ... A square is a special rectangle that has all four sides congruent. A kite has two consecutive sides congruent. The angle between these two sides could be a right angle, but there would only be one right angle in the kite.

### What is a quadrilateral but 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.

### What shape is a parallelogram?

A parallelogram is **a quadrilateral with 2 pairs of parallel sides**. In these figures, sides of the same color are parallel to each other. A shape with four sides of equal length. The shape has two sets of parallel sides and does not have right angles.

### What three shapes can make a parallelogram?

The four shapes that meet the requirements of a parallelogram are **square, rectangle, rhombus, and rhomboid**. A rhombus looks like a slanted square, and a rhomboid looks like a slanted rectangle. Squares and rectangles of a parallelogram form four right angles.

### Is trapezoid a parallelogram?

They agree that a parallelogram is a quadrilateral with two pairs of parallel sides. ... **A trapezoid has one pair of parallel sides** and a parallelogram has two pairs of parallel sides. So a parallelogram is also a trapezoid.

### Is trapezium a parallelogram?

A **trapezium is not a parallelogram** because a parallelogram has 2 pairs of parallel sides. But a trapezium only has 1 pair of parallel sides.

### Is a square a rhombus?

Square is **a rhombus** because as rhombus all the sides of a square are equal in length. Even, the diagonals of both square and rhombus are perpendicular to each other and bisect the opposite angles. Therefore, we can say the square is a rhombus.

### Why is a square a special parallelogram?

A square is a two-dimensional quadrilateral with four equal sides and four equal angles. It is a special **parallelogram in which all angles and sides are equal**.

### Is a square a parallelogram?

Since a square has 4 sides of equal length, it can also be classified as a rhombus. The opposite sides are parallel so a square can also be classified as a **parallelogram**.

### Is Kite a parallelogram?

In Euclidean geometry, a kite is a **quadrilateral** whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. In contrast, a parallelogram also has two pairs of equal-length sides, but they are opposite to each other instead of being adjacent.

### Are rectangles always parallelograms?

The vertices join the adjacent sides at 90° angles, which means the opposite sides of the rectangle are parallel lines. Since it has two sets of parallel sides and two pairs of opposite sides that are congruent, a rectangle has all of the properties of a parallelogram. That's why **a rectangle is always a parallelogram**.

### Is every rectangle a rhombus?

No, **every rectangle is not a rhombus**.

### How do you classify a parallelogram?

**Quadrilaterals: Classification**

- A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel .
- A rhombus is a parallelogram with four congruent sides. ...
- A square can be defined as a rhombus which is also a rectangle – in other words, a parallelogram with four congruent sides and four right angles.

### Are diagonals of parallelogram equal?

The diagonals of **a parallelogram are NOT equal**. The opposite sides and opposite angles of a parallelogram are equal.

### What is special parallelogram?

A parallelogram is a **special type of quadrilateral that has equal and parallel opposite sides**. The given figure shows a parallelogram ABCD which as AB parallel to CD and AD parallel to BC. Also, AD = BC and AB = CD.

### What is the diagonal of a parallelogram?

The diagonals of a parallelogram are **the connecting line segments between opposite vertices of the parallelogram**. Using this formula we can find out the lengths of the diagonals only using the length of the sides and any of the known angles.
