Answer:

Irregular Polygons

Step-by-step explanation:

Let's us first learn the definition of a polygon. A polygon is a closed shape figure that has a minimum of three sides and three vertices. The term ‘poly’ means ‘many’ and ‘gon’ means ‘angle’. Thus, polygons have many angles. The perimeter and area of polygon depend upon its types.

The classification of polygons is described based on the numbers of sides and vertices. For example, a polygon as four sides and four angles, then it is quadrilateral. The polygons up to 12 sides are the important ones. We are going to learn here polygon’s types based on the number of sides of the closed figure along with examples and diagrams.

Polygons are classified into various types based on the number of sides and measures of the angles. They are:

  1. Regular Polygons
  2. Irregular Polygons
  3. Concave Polygons
  4. Convex Polygons
  5. Trigons
  6. Quadrilateral Polygons
  7. Pentagon Polygons
  8. Hexagon Polygons
  9. Equilateral Polygons
  10. Equiangular Polygons
  • Regular Polygon

In a regular polygon, all the sides of the polygon are equal, and all the interior angles are the same. For example, a regular hexagon has six equal sides, and all its interior angles measure to 120 degrees.

  • Irregular Polygon

A polygon with an irregular shape. It means the sides and angles of the polygon are not equal.

  • Convex Polygon

In a convex polygon, the measure of the interior angle is less than 180 degrees. It is exactly opposite to the concave polygon. The vertices of a convex polygon are always outwards

  • Concave Polygon

In a concave polygon, at least one angle measures more than 180 degrees. The vertices of a concave polygon are inwards as well as outwards.

  • Trigons

Trigons are polygons who have three sides. They are nothing but triangles. These trigons or triangles are further classified into different categories, such as:

  1. Scalene Triangle: All sides are unequal
  2. Isosceles Triangle: Two sides are equal
  3. Equilateral Triangle: All the three sides are equal and all angles measures to 60 degrees.
  • Quadrilateral Polygon

Quadrilateral polygon is also called a four-sided polygon or a quadrangle. The different types of the quadrilateral polygon are square, rectangle, rhombus and parallelogram.

  • Pentagon Polygon

The five-sided polygon is called pentagon polygon. When all the five sides of the polygon are equal in length, then it is called regular pentagon otherwise irregular pentagon.

  • Hexagons

Another type of polygon is the hexagon which has 6 sides and 6 vertices. A regular hexagon will have equal 6 sides and all its interior and exterior angles also measure equals.

  • Equilateral Polygons

The polygons whose all the sides are equal are called equilateral polygons, for example, an equilateral triangle, a square, etc.

  • Equiangular Polygons

The polygons whose all the interior angles are equal such as a rectangle are called equiangular polygons.

Answer:

It's an Irregular Quadrilateral

Step-by-step explanation:

It has 4 sides and the length of the sides of the Quadrilateral is not equal. This makes it irregular.

If a triangle has a heig of 14 inches and base of 9 inches whats its area?
vlada-n [284]

Answer:

63 inches

Step-by-step explanation:

the formula for the area of a triangle is

a = 1/2 bh

plug in the numbers

a = 1/2(9)(14)

9 times 14 is 126

a = 1/2(126)

half of 126 (or 126 divided by 2)

area = 63 inches

A sealed tank of water measures 10cm x 8 cm x 40cm. When it stands on one
Pavel [41]

Answer:

New height = 6

Step-by-step explanation:

The water is going to be the same volume no matter how the tank is orientated.

So you can do this 2 ways.

First way

Find the volume in the tank when the water goes up 24 cm on the height.

V = L*W*h

L = 8

W = 10

H = 24

V = 1920 cm^3

Now do it using the

L = 40

W = 8

h = ?

1920 = L * W * h

1920 = 40 * 8 * h

1920 = 320 * h

h * 320 = 1920

h = 1920/320

h = 6

Or you can do it without finding the 1920

L*W*h = L1 * w1 * h1

8*10*24 = 40 * 8 * h                                The 8's cancel

10*24 = 40*h                                           Divide both sides by 10

24 = 4h                                                    Divide by 4

h = 6

Same as you got before.

The cafeteria serves pizza every 10 days and corn every 4 days. If they are serving pizza and corn today, in how many days will
alisha [4.7K]

Answer:

Well it would be 100 days

Step-by-step explanation:

Because they had pizza every ten days and if you add 5 days a week that's 50 days they sell pizza. If your talking corn they sell it every 4 days times 5 days a week that's 20 days of corn. Then you do 50 x 20 and then you get 100 days of pizza and corn, so it would be 100 days before they sell pizza and corn together again!
