Examples of Irregular Polygons

There are various different examples of irregular polygons including scalene triangles, isosceles triangles, right triangles, rectangles, irregular pentagons, irregular hexahexagon many more.

Scalene Triangle

Triangle in which all the three sides are different is called as scalene triangle.

Some Formulas of Scalene Triangle

Below are some formulas related to scalene triangle.

• Area of scalene triangle is given by Heron’s formula.

Area = √[s (s-a) (s-b) (s-c)]

where,

• a, b and c are sides of scalene triangle
• s = (a + b + c) /2

• Perimeter of Scalene Triangle = Sum of All Three Sides.

Isosceles Triangle

Triangle in which two sides are equal is called as isosceles triangle.

Some Formulas of Isosceles Triangle

Below are some formulas related to isosceles triangle.

• Height of isosceles triangle = √[(a² – b²)/4]
• Area of isosceles triangle = (1/2) × base × height
• Perimeter of isosceles triangle = sum of all three sides

Right Triangle

Triangle with one of its angles as right angle is called right triangle.

Some Formulas of Right Triangle

Below are some formulas related to right triangle.

• Area of Right triangle = (1/2) × base × height
• Perimeter of Right triangle = Base + Perpendicular + Hypotenuse
• Pythagoras theorem: (Hypotenuse)² = (Base)² + (Perpendicular)²

Rectangle

Quadrilateral whose all angles and opposite sides are equal is called as rectangle.

The four sides of rectangle include two length and two breadths. The measure of length and breadth can be equal and unequal.

Some Formulas of Rectangle

Below are some formulas related to rectangle.

• Area of the rectangle = length × breadth
• Perimeter of rectangle = 2(length + breadth)

Irregular Pentagon

Pentagon whose sides are not equal is called as the irregular pentagon.

Irregular Hexagon

Hexagon whose sides are not equal is called as irregular hexagon.

Irregular Polygons are polygons that don’t have all their sides equal. All the angles are not of equal measure in irregular polygons. Some examples of irregular polygons include the right triangle, isosceles triangle, scalene triangle, rectangle and many more.

In this article, we will explore irregular polygons, properties of irregular polygons, types of irregular polygons and irregular polygon formulas. We will also discuss the difference between regular and irregular polygons and solve some examples related to irregular polygons. Let’s start our learning on the topic “Irregular Polygons “.
