**Answer**

Answer and explanation: Of the claims made about a parallelogram, the one that is not always true is that the diagonals of the parallelogram are congruent with one another. Considering that a parallelogram is defined as two congruent and parallel sides, we may conclude that both the second and fourth propositions are always true.

### Furthermore, what attribute of a parallelogram is not true for all parallelograms?

1) Angles that are diametrically opposed are congruent. Contiguous angles are supplementary in nature. 3)Congruent sides are found on opposing sides.

### Which of the following is also true for all parallelograms?

Parallaxograms are rectangular figures with four sides that are parallel to one another on a plane. It is known from the characteristics of a parallelogram that the opposing sides and opposite angles of a parallelogram are equal in length and width. In addition, the diagonals of a parallelogram are bisected by one another.

### What is true of any parallelogram as a result of this?

The qualities of a parallelogram are essentially the facts that are true about it in terms of geometry. The following are the characteristics of the parallelogram: By definition, opposite sides are parallel to one another. The opposing sides are congruent with one another. Angles that are diametrically opposed are congruent.

### Is a rhombus considered a parallelogram?

A rhombus is a parallelogram with four congruent sides that is defined as follows: WHEN A PARALLELOGRAM IS A RHOMBUS, then each diagonal bisects a pair of opposing angles on the parallelogram. THEOREM Inversely, if a parallelogram features diagonals that bisect a pair of opposing angles, the parallelogram is referred to as rhombus.

### Is a rectangle considered a parallelogram?

A rectangle has two sets of opposing sides that are parallel to one another, as well as four right angles. Because it has two sets of parallel sides, it is sometimes referred to as a parallelogram. No, since a rhombus does not have to have four right angles to be considered a rhombus.

### What is the best way to prove a parallelogram?

You must use one of the five methods listed below to demonstrate that a quadrilateral is a parallelogram. Demonstrate that both pairs of opposing sides are parallel to one another. Demonstrate that the pairings of opposing sides are congruent on both sides. Demonstrate that a pair of opposed sides is both congruent and parallel by constructing a proof. Demonstrate that the diagonals are bisected by each other.

### Is it true that the diagonals of a parallelogram are perpendicular?

All of the characteristics of a parallelogram are applicable (the ones that matter here are parallel sides, opposite angles are congruent, and consecutive angles are supplementary). By definition, all parties are in agreement with one another. The diagonals cut the angles in half. The diagonals are perpendicular bisectors of each other, and they are connected by a line.

### Is a kite a parallelogram, or is it not?

Kites are quadrilaterals having two disjoint pairs (no side is in both pairs) of equal-length, adjacent (sharing a vertex) sides that are adjacent (share a vertex) to one another. A parallelogram, like a rectangle, has two sets of equal-length sides, but they must be opposite each other rather than contiguous.

### In what ways do parallelograms differ from other shapes and patterns?

Parallelism exists between two pairs of opposing sides (by definition). Two pairs of opposing sides have the same length as one another. Two sets of angles that are diametrically opposed are equal in size. The diagonals cut each other in half.

### What are the characteristics of a parallelogram?

A parallelogram is a flat geometry with opposing sides that are parallel and equal in length, similar to a rectangle. Because the angles “a” and “b” total up to 180°, they are referred to as supplementary angles. Parallelograms include squares, rectangles, and rhombuses, among other shapes.

### What is the total number of different varieties of parallelograms?

three

### In a parallelogram, are the diagonals all the same length?

It is easy to observe that the angles across the common side (in this case, the diagonal) of a parallelogram are equal when it is split into two triangles. This demonstrates that the angles on each side of a parallelogram are equal as well. An asymmetrical parallelogram has diagonals that are not equal in length.

### Is a hexagon a parallelogram, and if so, how?

A Parallelogram is defined as a quadrilateral, which means that it must have precisely four sides, according to the definition. This particular element is often missed, with just the two sets of parallel sides being highlighted. However, since every Hexagon has six sides, a hexagon can never be considered a Parallelogram.

### What is the best method for determining the height of a parallelogram?

Height Calculation Formula The method for determining the area of a parallelogram may also be used to calculate the height of a parallelogram. If you divide both sides of the formula by b, you will get the formula for h, which is the height of the object.

### Is a diamond a parallelogram, and if so, how?

A rectangle is a parallelogram with four sides that are opposing, parallel, and congruent to one another. A rhombus is a shape with four equal sides. However, the corners do not form right angles, despite the fact that the opposing sides are parallel. A rhombus is a form that looks like a diamond when you look at it closely.

### What are the six qualities of a parallelogram, and what do they mean?

Parallelograms have six significant qualities that you should be aware of: In this case, the two sides are congruent (AB = DC). In this case, the opposing angels are congruent (D = B). Angles formed by successive angles called supplementary (A + D = 180°).
