# Kinds Of Triangles According To Angles

Triangles play the fundamental part into mathematics. There are several kinds of triangles according to angles in which they are classified. Everyone knows that triangle consists of three angles and three sides. The total sum of all angles of a triangle should be 180_ and then only it would be considered as a triangle. There are three major kinds of triangles according to angles viz. acute triangle, obtuse triangle, and right angle triangle. These three types are categorized on the basis of angles.

The world of geometry and algebra is incomplete without the presence of triangles. There are ample numbers of calculations that can be solved using the diagrams of triangles. Triangle is a term that is related with three sides and three angles. Thus, the name is given as ‘Tri’angle.

There are many formulas derived on the basis of types of angles. Triangles can either be categorized on thee basis of their sides or in accordance with the angles. There are three types of triangles that are categorized on the basis of sides. These types include equilateral triangle, scalene triangle, and isosceles triangle.

The actual concept of triangle rotates around the sum of angles exhibited by particular triangle.

Let’s take a deep look on kinds of triangles according to angles.

Acute triangle:

In acute angle, all angles are less than 90 degrees. It should be noted that acute angles have unique characteristics of having all angles less than 90 degrees. The sides of this triangle may not be the same. The shape and size of triangle never gets counted in case of kinds of triangles according to angles. Thus, acute angle is a first type of triangle which is categorized on the basis of angles. After acute triangle, obtuse and right angle triangles are the next types of triangles that are categorized on the basis of kinds of triangles according to angles.

Obtuse triangle:

These triangles are completely different from the acute triangles. In this triangle, one angle is measured as greater than 90 degrees but less than 180 degrees. The sides of this triangle may be different and varying in length. Obtuse triangle is one of the kinds of triangles according to angles. This triangle and its definition is pretty simple to understand and anyone with good memory could remember it without many hassles.

Equiangular triangle:

Triangle that has all equal angles is called as equiangular triangle. This triangle consists of three equal sides as well as three equal angles. The actual concept and definition of this triangle is easiest to remember. In equiangular triangle the sum of all angles is equal to 180 degrees which means that each angle creates an angle of 60 degrees. These are nothing but the equilateral triangle.

While learning kinds of triangles according to angles it becomes necessary to remember the definition of each triangle. All these triangles are major types of triangles that are categorized on the basis of angles. Along with these types, it is necessary to remember the types of triangles that are categorized on the basis of sides.
