Triangle Squeeze-Them-In Puzzle

This 3-in-1 Squeeze-Me-In puzzle comes with a triangular board, three small pieces (one triangle, one parallelogram, and one square), and nine large pieces. Before you solve it, the three small pieces are tucked into the three small empty cutouts, and the nine large pieces are arranged to fit snugly into the square board. The challenge here is to fit one of the tiny pieces into the big square board, along with the nine bigger pieces, without any of them overlapping. You’ll probably have to shuffle, turn, and flip all ten pieces to get it right. This puzzle is a triple threat because it has three small pieces, and each one is its own puzzle to solve. for details, see HERE
