# What is an equilateral quadrilateral?

## What is an equilateral quadrilateral?

In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length.

### What is a equilateral for kids?

The equilateral triangle is a triangle with sides that are all the same length. The three interior angles are all the same too. If we use what we learned above, that all the angles must total 180 degrees, then each angle in an equilateral triangle is 180/3 = 60 degrees.

What is an example of an equilateral quadrilateral?

An equilateral quadrilateral, i.e. the one with all sides equal, is a rhombus. In a square, rectangle, or rhombus, the opposite side lines are parallel. Kite and dart are examples of orthodiagonal quadrilaterals, i.e. quadrilaterals with perpendicular diagonals.

What does equilateral triangle mean for kids?

equilateral triangle. • a triangle with 3 equal sides and 3 equal angles.

## What is a quadrilateral that is equilateral but not equiangular?

A quadrilateral can be equiangular but not equilateral (a rectangle) or equilateral but not equiangular (a rhombus). A square, however, is both. All sides of a square are the same length (equilateral) and all its angles have the same measure (equiangular).

### What is a equilateral parallelogram called?

Explanation: A rhombus is: “A quadrilateral with both pairs of opposite sides parallel and all sides the same length, i.e., an equilateral parallelogram.”

What is meaning of equilateral in math?

mathematics. : a triangle in which all three sides are the same length.

What’s the difference between equilateral and isosceles triangles?

In an equilateral triangle, all three sides are the same length. In an isosceles triangle, two sides are the same length. An isosceles triangle may be right, obtuse, or acute (see below). In a scalene triangle, none of the sides are the same length.

## How do you explain quadrilaterals?

In geometry, a quadrilateral can be defined as a closed, two-dimensional shape which has four straight sides. The polygon has four vertices or corners. We can find the shape of quadrilaterals in various things around us, like in a chess board, a deck of cards, a kite, a tub of popcorn, a sign board and in an arrow.

### How can we use quadrilaterals in real life?

Examples could be: table top, book, picture frame, door, baseball diamond, etc. Since these shapes are so common, quadrilaterals are also used in graphic art, sculpture, logos, packaging, computer programming and web design; in fact, there are few areas of daily life where there are no examples of quadrilaterals.

What is equilateral triangle explain?

: a triangle in which all three sides are the same length.

What is called equilateral triangle?

In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

## Do quadrilateral have to have all equal sides?

The only regular (all sides equal and all angles equal) quadrilateral is a square. So all other quadrilaterals are irregular. Quadrilateral definitions are inclusive. Example: a square is also a rectangle. So we include a square in the definition of a rectangle.

### What quadrilateral has two pairs of equal sides?

A parallelogram having all sides equal is called a rhombus. A parallelogram whose each angle is a right angle, is called a rectangle. A square is a rectangle with a pair of adjacent sides equal. A quadrilateral is a kite if it has two pairs of equal adjacent sides and unequal opposite sides.

What does quadrilateral have equal sides?

Quadrilateral Properties All the sides of the square are of equal measure The sides are parallel to each other All the interior angles of a square are at 90 degrees (i.e., right angle) The diagonals of a square perpendicular bisect each other

How do you classify a quadrilateral?

Quadrilaterals can be classified into different types, depending on the formation of sides and the nature of interior angles. A quadrilateral in which a set of non-adjacent sides are parallel, is named as trapezoid or trapezium.
