Characteristics of a Triangle

Triangle is a polygon and is the simplest type of polygon. A triangle always has three sides to it. In mathematics, polygons and their functions are studied under geometry which is a branch of mathematics. The article provides information on triangles, their types, and their characteristics. The area of a triangle definition has also been provided in the following section. Area of a triangle definition implies the meaning of area or surface of a triangle. Polygons are formed by putting together several triangles together. The area in the case of a triangle is calculated based on its perimeters or sides.

Area of a Triangle Definition

Triangle has a surface that is calculated on its perimeters or its three sides. The area of a triangle definition covers the summation of all the sides of the polygon together. For a triangle, the perimeters or three sides are taken together and calculated together. The area of a triangle definition is obtained from the product of height and base of the triangle and then halving it. Mathematically it is represented as A = ½ *b* h where b = base and h = height. This mathematical formula applies to every type of triangle. The height and base of a triangle are always perpendicular to one another. 

Characteristics of a Triangle

The cumulative features of a triangle are:

• It is a shape that is enclosed on all of its sides
• A triangle always has three sides
• height and base of a triangle is always perpendicular to one another
• Triangle is a polygon
• Triangle has three angles
• The summation of the angles equals 180 degrees
• Three vertices 
• The summation of three sides yields the perimeter of the triangle

The area of a triangle definition is connected with the trigonometrical function in the study of triangles and their areas. 

Area of Triangle Calculation

The area of triangle calculation is based on the area formula of the triangle. The area triangle denotes the region that is enclosed between its three sides. Mathematically it is represented as A = ½ *b* h where b = base and h = height. The unit of measurement that is written for the area is in square units like cm², in², m². To calculate the area of a particular triangle the following formulas can be adopted:

• Trigonometric functions (2 sides are known and their angle)
• Heron formula (summation of three sides of the triangle)
• Basic formula (A = ½ *b* h)

Triangles Types

The types in a triangle are based on either their angles or lengths. These are all a part of the triangle’s characteristics.  Based on their angles, triangles are divided into 3 types acute (all angles are less than 90 degrees), right (one side has 90 degrees), and oblique (one angle is more than 90 degrees). Based on the lengths, triangles can be divided into three which are where all three sides are equal (equilateral), two sides are equal (isosceles) and no side is the same (scalene). 

Conclusion

Thus, the characteristics of a triangle have been studied briefly here. The characteristics of a triangle are straightforward to follow. Triangles are polygons and their simplest form. A polygon is made up of several triangles. There are different kinds of triangles. The triangle perimeter is obtained from adding up all the sides together and its area is equal to half of the result of base and height.
