Perpendicular diagonals are two diagonals of a polygon that intersect forming four right angles, that is 90 ° wide angles. The diagonal of a polygon is a segment that joins two non-consecutive vertices of the polygon, that is, it is a segment that joins two vertices not belonging to the same side.

## In which Quadrilateral are the diagonals perpendicular to each other?

A rhombus has diagonals that are perpendicular to each other and angle bisectors. If a parallelogram has perpendicular diagonals, then it is a rhombus. If a parallelogram has a diagonal bisecting an angle, then it is a rhombus.

## How can the diagonals be between them?

In geometry, the segment that joins two non-consecutive vertices of a polygon or a polyhedron is called a diagonal. The diagonals can be internal or external to the perimeter of the polygon or to the volume of the polyhedron, in particular they are all internal if the figure is convex.

## In which parallelogram are the diagonals perpendicular?

The rhombus is a parallelogram with congruent sides: its diagonals are perpendicular, they are bisectors of the angles and their meeting point is the center of the inscribed circumference.

## Why are the diagonals of the rectangle not perpendicular?

The generic rectangle is a parallelogram having sides equal to two by two. … In a generic rectangle (so that it is not square) the diagonals are equal, not perpendicular and do not represent the bisectors of the angles.

### How are the diagonals in a rectangle?

A rectangle has two congruent diagonals, i.e. the two diagonals have the same length. The diagonal of a rectangle is calculated by extracting the square root of the sum between the square of the base and the square of the height of the rectangle. and descends from the Pythagorean theorem.

### In which figure do the diagonals cut in half?

Similarly, if segment BO and segment OD have the same length, it means that point O divides the diagonal BD in half exactly. This means that in each parallelogram the DIAGONALS are CUT in HALF.

### Which parallelogram has the same diagonals?

Theorem: A parallelogram having congruent diagonals is a rectangle.

### How to prove that the diagonals of a rhombus are perpendicular?

in each rhombus the diagonals are perpendicular

they have: AO = OC because in a parallelogram the diagonal is divided in half AB = BC by hypothesis.

### How are the diagonals of a parallelogram to each other?

Each of the two segments that unites two opposite vertices of a parallelogram, which has two diagonals, is said to be diagonal of the parallelogram: one is called the major diagonal and the other the minor diagonal. the height relative to the oblique side.

### Why does the square have perpendicular diagonals?

Perpendicular diagonals are two diagonals of a polygon that intersect forming four right angles, that is 90 ° wide angles.

### How to prove that the diagonals of the rectangle are equal?

in each rectangle the diagonals are congruent

they have: ABC ^ = BCD ^ by hypothesis. AB = CD because opposite sides of a parallelogram. the BC side in common.

### Which geometric figure has congruent diagonals?

The square is a particular type of rhombus which has all the angles congruent, and the two diagonals congruent.

### What are the quadrilaterals that have the same diagonals?

All quadrilaterals (n = 4) instead have 2 diagonals, polygons with 5 sides have 5, those with 6 sides have 9, and so on.

### Which polygon has all obtuse angles?

Angles: Opposite angles are congruent (i.e. equal) to each other. The parallelogram has 2 acute angles and 2 obtuse angles.

### What are the quadrilaterals with the diagonals that bisect?

A quadrilateral is a parallelogram if and only if its diagonals bisect, i.e. each divides the other into two congruent segments. A quadrilateral is a parallelogram if and only if all pairs of consecutive interior angles consist of additional angles.

### How to prove that a rhombus?

A rhombus is a parallelogram that has four congruent sides. The necessary and sufficient condition for a parallelogram to be a rhombus is that it has diagonals perpendicular to each other and that these are angle bisectors.

### How do you find the diagonals of a rhombus knowing the area?

Calculating rhombus diagonals with the area

To calculate the size of a diagonal, divide the area of ​​the rhombus twice by the size of the other diagonal.

### How do you find the largest diagonal of a diamond?

You know that the two diagonals divide the rhombus into 4 right triangles. Therefore, to know its value, apply the Pythagorean theorem. Therefore, the greater diagonal (whose half in the theorem represents the greater cathetus), is obtained from the square root of the side (hypotenuse) to the second.

### Which parallelogram has congruent opposite angles?

The rhombus has all the characteristics we have already talked about for parallelograms, therefore the opposite angles congruent, the opposite sides parallel, but, in addition, the four sides are congruent.

### How many diagonals can you draw in a parallelepiped?

In a rectangular parallelepiped the four diagonals are equal. The volume of a parallelepiped is given by the product of the area of ​​one of its faces, taken as a base, by the corresponding height (distance between the base and the plane of the opposite face).

### Which parallelogram has 4 equal sides two perpendicular but not equal diagonals?

The square is a parallelogram having four congruent sides and four right angles. BCD diagonal side The square also has two diagonals, which are always perpendicular and congruent. Each side can act as a base, or as a height.

### How do you know if a quadrilateral is a rectangle?

In geometry, the rectangle is a quadrilateral that has all internal angles congruent to each other (and, consequently, right). … The square is a particular type of rectangle, characterized by having all four sides congruent.

### How do you find the diagonal of a rectangle having the perimeter?

To find the diagonal instead, we need to use the Pythagorean theorem. The diagonal would be the hypotenuse, while the base and the height are the two legs. To find the diagonal you need to take the square root of the sum of the base squared and the height squared. The diagonal of the rectangle is 29 cm.
