We started with just three triangles arranged into a specific shape. However, our goal is to form five triangles, so we need to do a few things that will allow us to complete the task successfully.
1. First, we need to remove the triangle above.
2. This means we need to move the two triangles from top to bottom,
3. So that they can be connected to the bottom triangle. Once that's done, we'll have a large triangle.
4. Next, we need to deal with the remaining triangle at the top.
5. We need to find a suitable position and fill it in the middle of the big triangle.
6. Make sure the triangle is perfectly embedded.
7. Finally, when we successfully complete these steps, we will see a pattern of five triangles appear in front of our eyes.
