## What is a parallelogram that is not a square or rectangle?

Here is an example when a parallelogram is a rectangle: Here is an example when a parallelogram is not a rectangle: 6. A trapezoid is a quadrilateral.

## What parallelogram is not a rectangle?

All four sides of a rhombus are congruent. Its properties include that each pair of opposite sides is parallel, also making it a parallelogram. In summary, all squares are rectangles, but not all rectangles are squares.

**What parallelogram is not a square?**

rhombus

Here is an example when a rhombus is not a square: 2. A triangle is a parallelogram.

**Which is not a square or rectangle?**

A quadrilateral is a rectangle if all four internal angles are 90∘ . A quadrilateral is a square if all four internal angles are 90∘ and all four sides are equal in measure. The above is a rectangle, as all four angles are 90∘ , but is not a square, as the two vertical sides are shorter than the two horizontal sides.

### Are all squares real rectangles?

All squares are rectangles, but not all rectangles are squares. All squares are rhombuses, but not all rhombuses are squares.

### How do you prove a square is a rectangle?

Definition: A square is a quadrilateral with all four angles right angles and all four sides of the same length. So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles.

**Why can’t a rectangle be a square?**

Definition: A square is a quadrilateral with all four angles right angles and all four sides of the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.

**Is a rectangle a parallelogram yes?**

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. However, a parallelogram is not always a rectangle.

#### Can you call a rectangle a parallelogram?

A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. On the other hand, not all quadrilaterals and parallelograms are rectangles. A rectangle has all the properties of a parallelogram, plus the following: The diagonals are congruent.
