The sum of the lengths of two sides of a triangle must be greater than the length of the third so the following eight triangles will do: (1,8,8), (2,7,8), (3,6,8), (3,7,7), (4,5,8), (4,6,7), (5,5,7) and (5,6,6).
The sum of the lengths of any two sides of a triangle must be greater than the third. After that, any relationship is specific to the triangle: its angles or other characteristics.
An isosceles triangle must have two sides of equal size.Since you have a side of 7 and 5, for it to be isosceles, your third side must be either 7 or 5.
The basic rule is that the sum of any two sides must be greater than the third. Then there are the sine and cosine rules which involve the lengths of the sides but also the angles.
If the lengths of each pair of them add to more than the length of the third, they can form a triangle. If not, they cannot.
If any of its 2 sides is not greater than its third in length then a triangle can't be formed.
For a triangle to exist, the sum of the shorter two sides must be longer than the third side.
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
The sum of the lengths of two sides of a triangle must be greater than the length of the third so the following eight triangles will do: (1,8,8), (2,7,8), (3,6,8), (3,7,7), (4,5,8), (4,6,7), (5,5,7) and (5,6,6).

An isosceles triangle must have two sides of equal size.Since you have a side of 7 and 5, for it to be isosceles, your third side must be either 7 or 5.
If you know the lengths of two sides then use Pythagoras' theorem to find the third side.
