WebJul 16, 2024 · Triangles can be grouped according to how many of their sides are equal: if all the three sides of a triangle have the same length, then it is an equilateral triangle.; if a triangle has two sides with the same length, then it is an isosceles triangle.; if all the three sides of a triangle have different lengths, then we have a scalene triangle. WebThe general formula for the area of a triangle whose side lengths are consecutive integers can be derived as follows: let x equal the length of the smallest side. The other two sides are then x + 1 and x + 2, and s (half the sum of the sides) is $\frac{3x + 3}{2}$.
