# Triangle: Interesting Ideas About The Figure Geometry is an important mathematical subject that everyone should be familiar with. Geometry has played an important role in shaping our planet into a better place over time.

Geometry covers a wide range of subjects. This branch of mathematics studies everything from basic shapes like squares, circles, and rectangles to more complex shapes like triangles and ellipses.

In this post, we will look at triangles, one of the most common shapes, as well as their various properties. The  Area of equilateral triangles is what we study in mathematics.

We’ve all heard of triangles, but only a few of us know what they are. Triangles are more than just their three-sided shape, as most people believe. They are endowed with a plethora of characteristics.

Some of the most common types of triangles we encounter in our daily lives are equilateral triangles, isosceles triangles, and scalene triangles. They are all unique in some way.

This article will focus on the different triangles and their properties. Let us go over the various types of triangles one by one, as well as the formulas used to calculate the area of a triangle.

## Types And Formulas To Calculate The Area of triangle

### Isosceles Triangle:

This triangle differs from the others mentioned previously. Two sides of an isosceles triangle are equal in length and differ from the third.

Because its two sides are the same length, the perimeter of an isosceles triangle is given by the formula 2a+b. Where a represents the length of two equal sides.

The area of an isosceles triangle can also be calculated because it is a closed figure. Its area is calculated using the formula 12*b*h, where b is the triangle’s base and its height.

### Scalene Triangle:

This triangle has three sides that are all different lengths. All of the sides of this triangle are unequal in length.

Because all three sides are unequal in length, one can deduce that all three angles of the triangle are also unequal. There is a formula for calculating the area of the scalene triangle as well.

### Equilateral Triangle:

In this triangle, all of the triangle’s sides are the same length. Because all of the sides are the same length, we can conclude that all of the angles in this triangle are equal.

The perimeter of an equilateral triangle is calculated by simply adding the triangle’s three sides. Consider a to be the length of the triangle.

Formula 3a is then used to calculate its perimeter. Let us now look at how to calculate the area of a triangle, which is useful in everyday life.

### Area of a Triangle:

It is critical to understand the area of a triangle. An equilateral triangle has a 60-degree angle. 3a2/ 4, where an is the triangle’s side, gives the area of an equilateral triangle.

This is one of the simplest methods for calculating the area of an equilateral triangle; all that is required is the value of any one of the triangle’s sides.

Equilateral triangle angles are congruent and exactly equal to 60 degrees. It is classified as a regular polygon because it has three sides.

A perpendicular line drawn from any of the vertices to the opposite sides of an equilateral triangle divides the side into equal lengths. It also divides the angle formed by the vertex into equal halves, each of which is 30 degrees from the point where the perpendicular line is drawn.

In the preceding essay, we looked in depth at various types of triangles and their properties. These mathematical concepts are critical, and mastery requires a thorough understanding of them.

There are several online platforms available to students to help them learn such arithmetic problems.
