How many types of triangle?
Answers
A triangle is a shape, or a part of two dimensional space. It has three straight sides and three vertices. The three angles of a triangle always add up to 180° (180 degrees). It is the polygon with the least possible number of sides.
There are a number of different types of triangles, such as equilateral triangles, right triangles, scalene triangles, obtuse triangles, acute triangles, and isosceles triangles

What is Triangle?
- Triangle is a closed figure which has three sides, three vertices and three angles.
- The sum of three angles of a triangle is equal to the 180 degree.
How many types of triangle?
There are three types of triangle on the basis of sides are:
- (1) Scalene Triangle
- (2) Isosceles Triangle
- (3) Equilateral Triangle
Scalence Triangle: All the sides are different in length.
Isosceles Triangle: Any two sides are equal.
Equilateral Triangle: All three sides are equal.
There are three types of triangle on the basis of angles are:
- (1) Acute Angled Triangle
- (2) Right Angled Triangle
- (3) Obtuse Angled Triangle
Acute angled triangle: Each angle is acute.
Right angled triangle: Any one angle is equal to 90 degree.
Obtuse angled triangle: Any one angle is obtuse.
