# 48 Types Of Triangle Based On Length Types Of Triangle Based On Length. If c is the length of the longest side, then a2 + b2 < c2, where a and b are the lengths of the other sides. A triangle is considered to be an equilateral triangle when all three sides have the same length.

Equilateral triangle, scalene triangle, and isosceles triangle. Also, the sum of all three internal angles of a triangle equal to 180°. A triangle having three sides of different lengths.

### Let Us Discuss Them One By One.

The triangles table is described as follows: A triangle with 2 equal sides is called an isosceles triangle. It's a triangle with sides of equal length.

### What Is A Triangle Called?

We can classify triangles into 3 types based on the lengths of their sides: Classification of triangles according to the length of their sides. How do you tell what type of triangle it is based on side lengths?

### A Triangle Having All Three Sides Of Equal Length.

No side will be equal in length to any of the other sides in such a triangle. A scalene triangle has all side lengths of different measures. Let us now understand each type:

### According To The Lengths Of Their Sides, Triangles Can Be Classified Into Three Types Which Are:

Equal lengths of a triangle are shown by making an arc on each side. Each row in the table denotes the lengths of each of a triangle's three sides. All the properties of a triangle are based on its sides and angles.

### What Are The 3 Types Of Triangles Based On The Lengths Of Their Sides?

In such triangles, the length of each side is not equal to any other side. A = 2, b = 2, c = 2. The most common classifications are described on this page.
