🧩 Level Info

• Level Number: 108
• Problem Statement: Fit a square into the red square frame. Fit two triangles into the square frame.
• Difficulty: Normal

🎯 Objective

Fit a square into the red square frame and fit two triangles into the other square frame so that they all fit precisely.

📝 Steps to Solve

1. First, identify the "red square frame" on the screen. This is where you should initially place the square.
2. Without tapping the nearby standalone square, drag it directly over to the red square frame, aligning it precisely within.
3. Once the square is correctly positioned within the red frame, release your finger to set it in place.
4. Next, locate the "square frame" (the non-red frame) and prepare to fit two triangles into it.
5. Drag one of the two triangles and place it on one side (e.g., bottom left) of the square frame, pushing it to the edge without extending beyond it.
6. Then drag the remaining triangle and align its orientation with the first one. Place them so that their hypotenuses form a single square shape within the frame.
7. Once the two triangles form a neat square shape within the square frame, the puzzle is solved.

💡 Hints

• Firstly, focus on placing the square in the "red square frame" as per the instructions.
• You can easily drag the standalone square into the red square frame without any complicated operations.
• The remaining frame needs to have the "two triangles" fit in. Trying to place them individually won't work.
• Remember that two triangles can be combined into a new shape (a square).
• By matching the slanted sides of the triangles, you can stack them to form a "single square," which will fit the frame perfectly.

🧠 Analysis & Key Points

This problem is a puzzle involving "combination of shapes," requiring not just fitting shapes into designated frames, but also creatively combining multiple shapes into a new form. The first part is straightforward with placing the single square into the red square frame, but many players struggle with fitting the two triangles into the square frame in the second part. If you try placing the triangles individually, one will end up sticking out, leading to the misleading thought, "perhaps they both just won't fit?" The key is realizing that stacking the two triangles into one square shape allows you to fit them as a single piece into the frame. This problem tests whether you can recognize properties of the shapes (e.g., two right isosceles triangles forming a perfect square) and challenges spatial recognition and flexible thinking.

🔍 Common Mistakes

• Trying to insert the triangles individually into the square frame and giving up due to lack of space.
• Assuming a triangle sticking halfway outside the frame is "in" and getting confused without a correct judgement.
• Mistakenly attempting to place the square into the triangle frame and mismatching what goes where.
• Believing the triangles can be rotated, spending a long time dragging them in different directions, not realizing they simply need to be stacked without changing orientation.

🎉 Post-Clear Advice

The feeling of accomplishment from fitting the shapes neatly into the frames is gratifying in this stage. Going forward to the next level, expect an even more twisted mentality and other gimmicks, so continue advancing with flexible thinking such as "combining" and "stacking," just as you did this time.
