# Is a parallelogram always sometimes or never?

## Is a parallelogram always sometimes or never?

Explanation: For this question, all you need to know are the properties of each shape. Since the question is asking if a rectangle is a parallelogram, you would check to make sure all the properties of the parallelogram agree with those of a rectangle and since they all do, the answer is always.

Is a parallelogram a square always Sometimes Never?

Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms. This is always true. Squares are quadrilaterals with 4 congruent sides.

What is never a parallelogram?

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

### Is a parallelogram always sometimes or never a rhombus?

A rhombus is a quadrilateral with four congruent sides. Therefore, every rhombus is a parallelogram.

What is sometimes a parallelogram?

Â A parallelogram is a four-sided figure with two sets of parallel sides. A square is a parallelogram. This is always true. Â Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Parallelograms are quadrilaterals with two sets of parallel sides.

Are rectangles always parallelograms?

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.

## What shape is always a quadrilateral and never a parallelogram?

Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram. The correct answer is that all trapezoids are quadrilaterals.

Are parallelograms always similar?

This is always true. Â Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Parallelograms are quadrilaterals with two sets of parallel sides.

Is a parallelogram never sometimes or always a trapezium?

A trapezoid is a parallelogram. The diagonals of a rectangle bisect eachother.

### Why every parallelogram is not a rhombus?

Only the opposite sides of a parallelogram are equal. However, a rhombus has all its sides equal. So, every parallelogram cannot be a rhombus, except those parallelograms that have all equal sides.

Which quadrilateral will never be a parallelogram?

trapezoid
Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram. The correct answer is that all trapezoids are quadrilaterals.

Which of the following are not parallelograms?

Trapezium is not a parallelogram as it has only one pair of parallel sides.

## Is a square always a parallelogram?

A square is a parallelogram. This is always true. Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Parallelograms are quadrilaterals with two sets of parallel sides.

What are the opposite angles of a parallelogram?

In a parallelogram, opposite angles are supplementary. In a parallelogram, diagonals bisect each other. In a parallelogram, the diagonals create four isosceles triangles . In a rectangle, the diagonals are congruent . In a parallelogram, opposite angles are congruent . In a parallelogram, opposite angles are right angles .

How are the diagonals of a parallelogram and a rectangle similar?

In a parallelogram, the diagonals create four isosceles triangles . In a rectangle, the diagonals are congruent . In a parallelogram, opposite angles are congruent . In a parallelogram, opposite angles are right angles .

### What is the difference between a parallelogram and a rhombus?

In a parallelogram, you can find congruent alternate interior angles. In a rhombus, diagonals are perpendicular. In a square, the diagonals create four isosceles triangles. In a rhombus, the diagonals are congruent. A square is a parallelogram. A parallelogram is a rectangle.
