A triangle is a special type of polygon having 3 sides. The sum of interior angles of a triangle is always equal to 180 degrees and the angles opposite to the equal sides of a triangle are always equal to each other. The triangles can be classified into following six categories:

**Equilateral Triangle:**

In an Equilateral triangle, all sides are equal in length and the interior angles are of 60 degrees each.

**Isosceles Triangle:**

The two sides of an isosceles triangle are equal to each other. The angles opposite to the equal sides of an isosceles triangle are also equal to each other.

**Scalene Triangle:**

All the sides of a scalene triangle are unequal in length and therefore, all the interior angles are also different.

**Right angle Triangle:**

In a triangle, if one of the angles is 90 degree then it is called as right angle triangle. The side opposite to the 90 degrees will be the longest and is known as the hypotenuse.

**Acute angle Triangle:**

In a triangle, if all the interior angles are less than 90 degrees, then it is called an acute angle triangle.

**Obtuse Angle Triangle:**

In a triangle, if all the interior angles are greater than 90 degrees, then it is called obtuse angle triangle.
