# What is an irregular 4 sided polygon called?

## What is an irregular 4 sided polygon called?

Irregular Quadrilateral: a four-sided shape where no sides are equal in length and no internal angles are the same.

## How do you find the area of a 4 sided irregular polygon?

To find the area of such irregular quadrilaterals, follow a three-step strategy:

1. Divide the quadrilateral into two triangles by constructing a diagonal that does not disturb the known interior angle.
2. Calculate the area of each triangle, using formulas.
3. Add the areas of the two triangles.

What is the name of a 4 sided quadrilateral?

A quadrilateral is a four-sided two-dimensional shape. The following 2D shapes are all quadrilaterals: square, rectangle, rhombus, trapezium, parallelogram and kite.

### What are the different types of 4 sided polygons?

There are 6 different 4 sided polygons, or quadrilaterals that receive their own names. They are rectangles, squares, parallelograms, rhombuses, kites and trapezoids.

### What is the area of an irregular quadrilateral?

The area of any irregular quadrilateral can be calculated by dividing it into triangles. Example: Find the area of a quadrilateral ABCD whose sides are 9 m, 40 m, 28 m and 15 m respectively and the angle between the first two sides is a right angle. The area of the quadrilateral ABCD =(180+126)=306 square meters.

What is an irregular quadrilateral?

An irregular quadrilateral is a quadrilateral that is not regular, so all of its sides do not have equal length.

## What is a polygon with 4 sides and 4 angles called?

Meaning of Quadrilateral A quadrilateral is a polygon having four sides, four angles, and four vertices.

## What is a polygon with 4 equal sides?

The only regular (all sides equal and all angles equal) quadrilateral is a square.

What is an irregular polygon?

An irregular polygon is a 2D shape that has straight sides that are not equal to each other and angles that are not equal to each other.

### What is a concave polygon with 4 sides?

Yes, a star is a concave polygon. Because concave polygon should have at least 4 sides. Also, one or more interior angles should be greater than 180 degrees.

### What is the area of an irregular polygon?

To find the area of an irregular polygon you must first separate the shape into regular polygons, or plane shapes. You then use the regular polygon area formulas to find the area of each of those polygons. The last step is to add all those areas together to get the total area of the irregular polygon.

What is the area of the irregular polygon?

To find the area of an irregular shape, we first break the shape into common shapes. Then we find the area of each shape and add them. For example, if an irregular polygon is made up of a square and a triangle, then: Area of irregular polygon = Area of Square + Area of Triangle.

## What is Circumradius polygon?

The circumradius of a cyclic polygon is a radius of the circle inside which the polygon can be inscribed. Similarly, the circumradius of a polyhedron is the radius of a circumsphere touching each of the polyhedron’s vertices, if such a sphere exists.

## Why is it called an apothem?

The word “apothem” can also refer to the length of that line segment and come from the ancient Greek ἀπόθεμα (“put away, put aside”), made of ἀπό (“off, away”) and θέμα (“that which is laid down”), indicating a generic line written down. Regular polygons are the only polygons that have apothems.

What is a 4 sided polygon called?

A quadrilateral is a 4 sided polygon with connecting sides. A quadrilateral is like milk, which is a type of drink. Now each 4 sided shape that has a special name is like a flavor of milk. So chocolate milk is a special kind of milk and milk is a certain kind of drink.

### What is a 4 sided irregular shape called?

Any shape whose sides and angles are not of equal length is termed as an irregular shape. What is a 4 sided irregular shape called? Irregular Quadrilateral: a four-sided shape where no sides are equal in length and no internal angles are the same. All internal angles still add up to 360°, as with all other regular quadrilaterals.

An irregular polygon is a polygon with interior angles of different measures. In addition, the side lengths of an irregular polygon are also of various measurements. For finding the area of a polygon that is a little complex, or its formula is not defined, then, we split the figure into triangles, squares, trapezium, etc.

### How do you name a polygon with 5 sides?

We name polygons according to the number of sides they contain. For example, if the polygon has three sides, it is called a triangle. If the polygon has five sides, it is called a pentagon. If the polygon has six sides, it is called a hexagon and so on.
