**Asked by: Ms. Maud Sporer**

Score: 5/5 (8 votes)

The diagonals of **a parallelogram** bisect each other. ... In any parallelogram, the diagonals (lines linking opposite corners) bisect each other. That is, each diagonal cuts the other into two equal parts.

Moreover, Which shapes have diagonals that bisect each other?

**a parallelogram**, then its diagonals bisect each other.

...

**A square thus has all the properties of a rectangle, and all the properties of a rhombus.**

- Opposite sides are parallel.
- The diagonals meet each side at 45°.
- The diagonals are equal in length, and bisect each other at right angles.

Subsequently, question is, Has diagonals that bisect each other and are congruent?. If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a

**parallelogram**. If a quadrilateral is a rectangle, then it is a parallelogram. If a parallelogram is a rectangle, then its diagonals are congruent. If one angle of a parallelogram is a right angle, then the parallelogram is a rectangle.

Accordingly, Do diagonals bisect each other True or false?

**False**– diagonals don't have to be congruent or bisect each other. The diagonals of a rectangle bisect its angles.

How do you find the diagonals bisect each other?

**Expert Answer:**

- ABCD is a parallelogram, diagonals AC and BD intersect at O.
- In triangles AOD and COB,
- DAO = BCO (alternate interior angles)
- AD = CB.
- ADO = CBO (alternate interior angles)
- AOD COB (ASA)
- Hence, AO = CO and OD = OB (c.p.c.t)
- Thus, the diagonals of a parallelogram bisect each other.

### Are diagonals of rhombus equal?

A rhombus has all sides equal, while a rectangle has all angles equal. A rhombus has opposite angles equal, while a rectangle has opposite sides equal. ... The diagonals of a **rhombus intersect at equal angles**, while the diagonals of a rectangle are equal in length.

### Do diagonals of parallelogram bisect each other at 90 degree?

Now, for the diagonals to bisect each other at right angles, i.e. for ∠AOD=∠COB=90∘, the sum of the other two interior angles in both the triangles should be equal to 90∘. ... Hence, the **diagonals of a parallelogram bisect each other but not necessarily at right angles**. Thus, the given statement is false.

### Is every square a rhombus True or false?

A rhombus is a special type of parallelogram with opposite sides parallel, and all sides equal in length. **Every square is a rhombus**. True - The definition of a rhombus states that all sides are the same length. A square is a special type of rhombus because it has all sides the same length and 4 right angles.

### Is it true or false that opposite sides are congruent?

On a basic parallelogram, **opposite sides are congruent**. On a basic parallelogram, opposite sides are not congruent. On a basic parallelogram, consecutive angles are supplementary. On a basic parallelogram, consecutive angles are congruent.

### Do diagonals of parallelogram bisect angles?

Opposite angles are equal. Adjacent angles add up to 180 degrees therefore adjacent angles are supplementary angles. (Their sum equal to 180 degrees.) **The diagonals of a parallelogram bisect each other**.

### Does a rhombus have 4 right angles?

If you have a rhombus with four equal interior angles, you have **a square**. A square is a special case of a rhombus, because it has four equal-length sides and goes above and beyond that to also have four right angles. Every square you see will be a rhombus, but not every rhombus you meet will be a square.

### Are diagonals of rhombus angle bisectors?

Diagonals as Angle Bisectors

Since a rhombus is a parallelogram, opposite angles are congruent. One property unique to rhombi is that in any rhombus, the diagonals will **bisect the interior angles**. The diagonals of a rhombus bisect the interior angles.

### 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.

### Are diagonals bisect opposite angles?

The **diagonals bisect** the angles. The diagonals are perpendicular bisectors of each other.

### What are the 7 types of quadrilaterals?

Quadrilaterals - **Square, Rectangle, Rhombus, Trapezoid, Parallelogram**.

### Do rectangles always have diagonals that bisect opposite angles?

A rectangle is a quadrilateral in which all angles are right angles. A rectangle is a parallelogram, so its opposite sides are equal. **The diagonals of a rectangle are equal and bisect each other**.

### Is it true or false that a parallelogram?

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. ... Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms.

### Does a parallelogram have 6 sides?

A parallelogon must have an even number of sides and opposite sides must be equal in length and parallel (hence the name). A less obvious corollary is that **all parallelogons have either four or six sides**; a four-sided parallelogon is called a parallelogram.

### What divides a parallelogram into two congruent triangles?

**Diagonal AC** divides the parallelogram into two triangles △ABC and △ADC. In these two triangles, one side and two angles made on this side are equal. ... Therefore, it is proved that the diagonal of a parallelogram divides it into two congruent triangles and also opposite sides of a parallelogram are equal.

### Is square a rhombus if yes why?

A square is a **rhombus with all the angles equal (to 90°)**. ... All the angles are equal to 90°. The diagonals bisect each other at 90° The diagonals are equal.

### Is rhombus be a square justify it?

A rhombus is a quadrilateral with all sides equal in length. A square is a quadrilateral with all sides equal in length and all interior angles right angles. Thus a **rhombus is not a square** unless the angles are all right angles. ... A square however is a rhombus since all four of its sides are of the same length.

### Is the diagonals of parallelogram equal?

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

### Does a parallelogram have four right angles?

**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 are the 4 properties of a rhombus?

**A rhombus is a quadrilateral which has the following four properties:**

- Opposite angles are equal.
- All sides are equal and, opposite sides are parallel to each other.
- Diagonals bisect each other perpendicularly.
- Sum of any two adjacent angles is 180°
