A triangle is formed using three given side lengths. Do these lengths always forma unique triangle? Explain.​
ollegr [7]
No, these do not always forma unique triangles because it depends on what size your sides are because if you have 3 sides of the same length then that’s a equilateral and if you have two sides of the same length and one side that’s not then that would be an Isosceles triangle and if you had no sides of the same length then that would be a scalene triangle.
