Title: Show solutions to the equilateral triangles puzzle in C#

This post shows how to display manually found solutions to the puzzle Puzzle: Find the equilateral triangles in C#. This example uses the following code to define the puzzle's 25 solutions that I found manually.

// Define the solutions. Solutions = new List<int[]>(); Solutions.Add(new int[] { 0, 2, 3 }); Solutions.Add(new int[] { 0, 3, 1 }); Solutions.Add(new int[] { 1, 3, 4 }); Solutions.Add(new int[] { 2, 5, 6 }); Solutions.Add(new int[] { 2, 6, 3 }); Solutions.Add(new int[] { 3, 6, 7 }); Solutions.Add(new int[] { 3, 7, 4 }); Solutions.Add(new int[] { 4, 7, 8 }); Solutions.Add(new int[] { 5, 9, 6 }); Solutions.Add(new int[] { 6, 9, 10 }); Solutions.Add(new int[] { 6, 10, 7 }); Solutions.Add(new int[] { 7, 10, 11 }); Solutions.Add(new int[] { 7, 11, 8 }); Solutions.Add(new int[] { 0, 5, 7 }); Solutions.Add(new int[] { 1, 6, 8 }); Solutions.Add(new int[] { 3, 9, 11 }); Solutions.Add(new int[] { 10, 2, 4 }); Solutions.Add(new int[] { 5, 10, 3 }); Solutions.Add(new int[] { 2, 7, 1 }); Solutions.Add(new int[] { 6, 11, 4 }); Solutions.Add(new int[] { 8, 3, 10 }); Solutions.Add(new int[] { 4, 6, 0 }); Solutions.Add(new int[] { 7, 9, 2 }); Solutions.Add(new int[] { 0, 9, 8 }); Solutions.Add(new int[] { 1, 5, 11 });

This code defines the variable Solutions to be a list containing arrays of integers. It then adds to the list arrays containing the indexes of the points that make up the solutions.

You can try to find the solutions manually, but some of them are pretty hard to visualize. See the example Solve the equilateral triangles puzzle in C# to see how a program can find the solutions.
