Only 3: [1,4,4], [2,3,4] and [3,3,3] Remeber that the sum of the lengths of any two sides MUST be greater than the third side. So triangles like [1,2,6] cannot exist.
There is only one triangle whose sides have the given values. There can, of course, be countless copies.
There is one equilateral triangle with 3 equal sides of 7in

It is an isosceles triangle with 2 equal sides.
A pentagon has 3 triangles and 5 sides
it has 4 sides that are triangles
27. that is, if the triangles are not connected.
A triacontakaidigon is a polyhedron with 32 sides. If the sides are all triangles, then there are 32 triangles in a triacontakaidigon, but a triacontakaidigon does not need to have triangular shaped sides.
A triangle with two equal sides is an isosceles triangle and you can have as many as you like.
Only 3: [1,4,4], [2,3,4] and [3,3,3] Remeber that the sum of the lengths of any two sides MUST be greater than the third side. So triangles like [1,2,6] cannot exist.
A triangle has three sides, so six triangles have 6 * 3 = 18 sides altogether.
There is only one triangle whose sides have the given values. There can, of course, be countless copies.
There is one equilateral triangle with 3 equal sides of 7in
