## What shapes diagonals intersect at 90 degrees?

The diagonals of a rhombus bisect each other at right angles (90°).

## What shape has 4 90 degree angles?

rectangle

A rectangle is a quadrilateral with 4 right angles (90°). In a rectangle, both the pairs of opposite sides are parallel and equal in length.

**Does a rectangles diagonals cross at 90 degrees?**

the diagonals of a rectangle do not intersect in a right angle (they are not perpendicular). (Unless the rectangle is a square.) And the angles formed by the intersection are not always the same measure (size). Opposite central angles are the same size (they are congruent.)…

**Which of the following quadrilateral has its diagonals intersect at 90 degree?**

Explanation-:: Rhombus the quadrilateral that has two pairs of adjacent sides equal, and whose diagonals bisect at 90 degree.

### Which shape has two lines of symmetry and its diagonals intersecting at 90 degrees?

A rectangle has two pairs of equal sides. It has four right angles (90°). The opposite sides are parallel. The diagonals bisect each other.

### Do all quadrilaterals have 90 degree angles?

Name of Quadrilateral | Description |
---|---|

Rectangle | 2 pairs of parallel sides. 4 right angles (90°). Opposite sides are parallel and congruent. All angles are congruent. |

Square | 4 congruent sides. 4 right angles (90°). Opposite sides are parallel. All angles are congruent. |

Trapezoid | Only one pair of opposite sides is parallel. |

**Which shapes have diagonals that cross at right angles?**

A quadrilateral whose diagonals bisect each other at right angles is a rhombus.

**Which shape has 4 lines of symmetry 4 right angles 4 sides of equal length?**

Square

Square. A square has four lines of symmetry. It has rotational symmetry of order four.

## Which quadrilateral has two pairs of adjacent sides equal and its diagonals intersect at 90?

Rhombus the quadrilateral that has two pairs of adjacent sides equal, and whose diagonals bisect at 90 degree.

## Which of the following quadrilateral have equal diagonals?

Rhombus

Properties of the diagonals in quadrilaterals

Quadrilateral | Bisecting diagonals | Equal diagonals |
---|---|---|

Kite | See note 2 | See note 2 |

Rectangle | Yes | Yes |

Rhombus | Yes | No |

Square | Yes | Yes |

**How are the diagonals in a quadrilateral related to the angles?**

The diagonals bisect each other at right angles. A trapezium has one pair of parallel sides. A kite has two pairs of equal sides. It has one pair of equal angles. The diagonals bisect at right angles. The sum of interior angles in a quadrilateral is 360°. This fact and the properties of quadrilaterals can be used to calculate angles.

**What do you call a quadrilateral with no parallel sides?**

A trapezoid (called a trapezium in the UK) has a pair of opposite sides parallel. And a trapezium (called a trapezoid in the UK) is a quadrilateral with NO parallel sides: (the US and UK definitions are swapped over!)

### How many quadrilaterals have the same properties as a square?

There are six special quadrilaterals with different properties. A square has four sides of equal length. It has four right angles (90°). The opposite sides are parallel. The diagonals bisect each other at right angles. A rectangle has two pairs of equal sides.

### How are the diagonals of a square divided?

A square has two diagonals. The diagonal of a square is the line segment that is drawn between its opposite corners. The diagonals of a square are of the same length. Thus, they are also called congruent diagonals. Each diagonal bisects the other. The diagonal is divided into two equal parts when the diagonals intersect each other.
