Creating a working model to demonstrate the four types of triangles using a square box design that opens and hides information is a fantastic way to make learning interactive and engaging.

Here’s a step-by-step guide to making this model using cardboard, color paper, and chopsticks.

### Materials Needed:

• Cardboard (for the base, square boxes, and center label)
• Color paper (for covering and labeling)
• Scissors or craft knife
• Glue or hot glue gun
• Markers or pens
• Ruler
• Chopsticks (for the opening mechanism)
• Brass fasteners or paper fasteners (for attaching the rotating disks)

#### 1. Prepare the Base and Square Boxes

1. Base Preparation:
• Cut a large square piece of cardboard for the base. Cover it with color paper for a neat finish.
2. Square Boxes:
• Cut four smaller square pieces of cardboard. These will be the individual boxes representing each type of triangle.
• Cover these square pieces with color paper.
3. Center Label:
• Cut a smaller square piece of cardboard for the center label. Cover it with color paper and write “Types of Triangles” on it.

#### 2. Label and Attach Boxes

1. Label Boxes:
• Label each box with one type of triangle. The four types of triangles are:
• Equilateral Triangle
• Isosceles Triangle
• Scalene Triangle
• Right Triangle
2. Attach Boxes to the Base:
• Arrange the four labeled boxes around the center label on the base.
• Attach them to the base with glue, ensuring there is enough space for the opening and closing mechanism.

#### 3. Create Definitions and Examples

1. Definitions and Examples:
• On each box, write the definition of the triangle type and draw an example showing the angles and sides.
• Use color paper to make the examples visually appealing and easy to understand.

#### 4. Create the Opening Mechanism

1. Chopsticks Mechanism:
• Attach a chopstick to each box with brass fasteners or glue. This will act as a lever to open and close the information flap.
2. Information Flaps:
• Cut small pieces of cardboard to create flaps that can hide and reveal the information on each box.
• Cover the flaps with color paper and label them with “Open” on one side and “Close” on the other.

#### 5. Assemble the Model

1. Attach Information Flaps:
• Use brass fasteners to attach the flaps to the boxes. Ensure they can be easily lifted and lowered using the chopstick mechanism.
2. Position the Flaps:
• Ensure the flaps are evenly spaced and can open and close without obstruction.

#### 6. Final Touches

1. Ensure Functionality:
• Check that all flaps can easily open and close to reveal and hide the information on each box.
• Use different colors for different triangle types to make them stand out.
• Add small arrows or lines to clearly illustrate the sides and angles of each triangle.

### Example Layout:

• Top Left Box: Equilateral Triangle with definition and example (all sides equal, all angles 60°).
• Top Right Box: Isosceles Triangle with definition and example (two sides equal, two angles equal).
• Bottom Left Box: Scalene Triangle with definition and example (no sides equal, no angles equal).
• Bottom Right Box: Right Triangle with definition and example (one angle 90°).

### Steps to Make the Model:

1. Base Setup:
• Cut a large square piece of cardboard for the base and cover it with color paper.
• Attach the center label to the middle of the base.
2. Square Boxes:
• Cut four smaller squares for the triangle types and cover them with color paper.
• Label each box with the type of triangle and attach it around the center label.
3. Definitions and Examples:
• Write definitions and draw examples on each box.
• Attach flaps to each box using brass fasteners.
• Attach chopsticks to the flaps to act as levers.
4. Final Touches:
• Ensure all flaps open and close smoothly.
• Add visual aids and color coding for clarity.

By following these steps, you can create an interactive and educational model that demonstrates the four types of triangles effectively.
