Yes they can. Where the shortest sides added together are greater than the longest side, a triangle is formed.
Given an altitude of 12 units, an equilateral triangle has side lengths of 13.9 (13.85641) units.
A triangle with sides of 50, 50 and 60 units has an area of 1200 sq units.
There is only one equilateral triangle with a perimeter of 60 units. Its side lengths are integers.
Given side lengths of 14 units, the altitude is 12.1 (12.12436) units.
Three side lengths can form a triangle if they satisfy the triangle inequality theorem, which states that the sum of the lengths of any two sides must be greater than the length of the third side. This must hold true for all three combinations of the side lengths. For example, if the side lengths are (a), (b), and (c), then (a + b > c), (a + c > b), and (b + c > a) must all be true. If any of these conditions are not met, the side lengths cannot form a triangle.
The last side length could be between 4 units and 10 units inclusive.
Yes and the given lengths would form an isosceles triangle.
Given side lengths of 8 units, an equilateral triangle will have an altitude of 7 (6.9282) units.
1.5m
These dimensions do not form a triangle.
Its hypotenuse is 5 units in length
That depends on what the side lengths are. Until the side lengths are known, the triangle can only be classified as a triangle.
