Definition: A quadrilateral is a polygon with 4 sides.
How many four sided shapes are there?
There are six different types of quadrilaterals: parallelogram, rectangle, rhombus, square, kite, and trapezoid.
What shape has 4 sides with different lengths?
Quadrilaterals are polygons with four sides (hence the beginning “quad”, which means “four”). A polygon with non-equal sides is called irregular, so the figure that you are describing is an irregular quadrilateral. This figure has side lengths of 1, 2, 3, and 4 respectively, so it is an irregular quadrilateral.
What 3 shapes have 4 sides?
Quadrilaterals – Square, Rectangle, Rhombus, Trapezoid, Parallelogram.
What shape has 4 sides 4 angles?
A trapezoid is a quadrilateral with one set of parallel sides. It has 4 sides and 4 angles. A square is a four sided shape with 4 right angles. It’s opposite sides are parallel (2 sets) and all 4 sides are equal length.
Can a triangle have 4 sides?
A triangle is a primitive form of geometry (polygon) that can only have three sides in its simplest form.
What 2D shape has 4 sides?
A quadrilateral is a 2D shape with four sides. There are six special quadrilaterals with different properties.
What is an irregular 4 sided shape called?
Irregular Quadrilateral: a four-sided shape where no sides are equal in length and no internal angles are the same.
What shape has 4 sides but is not a square?
A quadrilateral is a polygon that has exactly four sides. (This also means that a quadrilateral has exactly four vertices, and exactly four angles.)
How does a pentagon look like?
A pentagon shape is a flat shape or a flat (two-dimensional) 5-sided geometric shape. In geometry, it is considered as a is a five-sided polygon with five straight sides and five interior angles, which add up to 540°. Pentagons can be simple or self-intersecting.
Is a rhombus a square?
SQUARE | RHOMBUS |
---|---|
A square has four lines of symmetry. | A rhombus has two lines of symmetry. |
What has 4 sides and no right angles?
Therefore, we can conclude that a quadrilateral with four equal sides and no right angles can be called a rhombus.
Is a rhombus a 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. … A rhombus with right angles is a square.
How many sides does a trapezoid have?
A trapezoid (also known as a trapezium) is a flat 2D shape with four straight sides. It has one pair of parallel sides which are usually the top and bottom sides.
How many sides are there?
Triangle – 3 Sides | Square – 4 Sides |
---|---|
Pentagon – 5 Sides | Hexagon – 6 sides |
Heptagon – 7 Sides | Octagon – 8 Sides |
Nonagon – 9 Sides | Decagon – 10 Sides |

How many sides does a decagon have?
In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a decagram.
What does a parallelogram look like?
Parallelograms are shapes that have four sides with two pairs of sides that are parallel. The four shapes that meet the requirements of a parallelogram are square, rectangle, rhombus, and rhomboid. A rhombus looks like a slanted square, and a rhomboid looks like a slanted rectangle.
What is the name of 4 side?
Sides | Names | |
---|---|---|
3 | trigon | triangle |
4 | tetragon | quadrilateral |
5 | pentagon | |
6 | hexagon |
Is a kite a trapezoid?
A kite is a quadrilateral with two pairs of adjacent sides of identical length. … A trapezoid (British: trapezium) can be a kite, but only if is also a rhombus. An isosceles trapezoid can be a kite, but only if it is also a square.
What shapes have straight sides?
A polygon is defined as a 2-dimensional shape with straight sides. Regular polygons have sides and angles that are all the same.
Is a starfish A pentagon?
Starfish: Almost all starfish have a fivefold radial symmetry or are shaped like pentagons.
What does a nonagon look like?
A regular nonagon is a nine-sided shape with equal sides and equal angles of 140 degrees each. Each interior angle measure of a regular nonagon is 140 degrees.
What is a shape with 99 sides called?
9. = ennea. 3 – 99 SIDES. To “construct” a name, we start with the prefix for the tens digit, follow it by “kai” (the Greek word for “and”), then follow it with the prefix for the units digit, and finally add “gon.”
Which quadrilaterals have 4 sides of equal length?
A rhombus is a quadrilateral with 4 equal sides. A shape with four sides of equal length. The shape has two sets of parallel sides and does not have right angles.
What is pentagon sides?
In geometry, a pentagon (from the Greek πέντε pente meaning five and γωνία gonia meaning angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting. A self-intersecting regular pentagon (or star pentagon) is called a pentagram.
Is triangle a quadrilateral?
Explanation: All triangles have three sides and three angles, hence the root word “tri” which means “three”. All quadrilaterals have four sides and four angles, hence the root “quad” meaning “four”. A triangle will never be a quadrilateral, because they do not share traits.
How many sides does a Nonagon have?
In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.
What is the kite shape?
In Euclidean geometry, a kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. … Kite quadrilaterals are named for the wind-blown, flying kites, which often have this shape and which are in turn named for a bird.
Which way is diagonally?
A diagonal line or movement goes in a sloping direction, for example, from one corner of a square across to the opposite corner.
What is a trapezium shape?
Meaning. A trapezoid is a quadrilateral with at least one pair of parallel sides. No other features matter. (In English-speaking countries outside of North America, the equivalent term is trapezium.) The parallel sides may be vertical , horizontal , or slanting .
Is a diamond a rhombus yes or no?
A diamond is a quadrilateral, a 2-dimensional flat figure that has four closed, straight sides. But a diamond is also categorized as rhombus, because it has four equal sides and its opposite angles are equal. And, because its opposite sides are parallel, it’s also considered to be a parallelogram.
Does a rhombus have 4 equal sides?
A rhombus is a parallelogram with four congruent sides. The plural of rhombus is rhombi . … A rhombus has all the properties of a parallelogram, plus the following: The diagonals intersect at right angles.
Is rectangle a rhombus?
A rectangle is a rhombus. A square is a parallelogram. A parallelogram is regular.
Does every parallelogram have 4 equal sides?
The classic parallelogram looks like a slanted rectangle, but any four-sided figure that has parallel and congruent pairs of sides can be classified as a parallelogram.
