Triangular Puzzle

One of the projects that I have made is a triangular puzzle. I made a design with many different sizes of rectangles and patterned them randomly. Then I split the pattern into 16 smaller triangles that together made one big triangle and left a border around the big triangle to hold the puzzle pieces. I overlapped some of the patterns onto the border so that you know where to put the smaller triangles and the puzzle is solvable. I wrote the number of where the pieces go on the back of the smaller triangles so that if it is not solved you know where the pieces should go.
