Given side lengths of 14 units, the altitude is 12.1 (12.12436) units.
Equilateral Triangle.
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
The answer depends on what instruments you have available. If you have a protractor, draw an inward facing 60 degree angle from each end of the line segment, and extend the lines until they meet.
Such a triangle would be impossible to construct with the given 3 dimensions because in order to construct a triangle the sum of its 2 shortest sides must be greater than the length of its longest side.
Given an altitude of 12 units, an equilateral triangle has side lengths of 13.9 (13.85641) units.
Given side lengths of 8 units, an equilateral triangle will have an altitude of 7 (6.9282) units.
Given a perimeter of 18 units, the resulting altitude is 5.2 (5.19615) units.
Given side lengths of 14 units, the altitude is 12.1 (12.12436) units.
There is only one distinct triangle.
Equilateral Triangle.
Equilateral triangles
A triangle can be constructed into any of the given formats.
The given dimensions will construct a triangle which will almost look like a straight line.
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
An equilateral triangle would fit the given description
No because the given dimensions would form an equilateral triangle
