In this post we write about making the types of triangles working model – TLM project – DIY

Creating a working model to showcase different types of triangles using a wheel and arrow design with cardboard and color paper can be an innovative and interactive way to learn about triangle classification.

Let’s build a simple 3D model to represent various types of triangles.

Materials needed:

- Cardboard (for the base and wheel)
- Color paper (for representing different types of triangles and arrows)
- Scissors
- Compass or a circular object for drawing the wheel
- Pen or pencil
- Glue or double-sided tape
- Marker pens or sketch pens

Step-by-step instructions:

- Base:
- Cut a circular piece of cardboard to serve as the base for the wheel.

- Wheel Design:
- Divide the circular cardboard into sections, each representing a different type of triangle (e.g., equilateral, isosceles, scalene, right-angled, etc.).
- Draw lines to create the segments for each type of triangle. Ensure the sections are evenly spaced around the wheel.

- Triangle Templates:
- Use color paper to create templates for each type of triangle.
- Draw and cut out an equilateral triangle, an isosceles triangle, a scalene triangle, a right-angled triangle, etc.

- Attaching Triangle Templates:
- Attach each triangle template to the corresponding section on the wheel using glue or double-sided tape.
- Ensure that the templates are securely fixed to the wheel and properly aligned with the sections.

- Arrow Design:
- Cut arrow-shaped pieces from color paper to represent indicators.
- Glue these arrow shapes at the edge of the wheel, pointing towards each triangle template.

- Labeling and Details:
- Use marker pens or sketch pens to label each section of the wheel with the type of triangle it represents (e.g., Equilateral, Isosceles, Scalene, Right-Angled).
- Label the arrows with corresponding text (e.g., “Equilateral,” “Isosceles,” etc.).

- Rotating Wheel:
- Attach the wheel to the center of the base using a pin or a brad so that it can rotate freely.

- Decorating the Model:
- Use markers or color paper to decorate the model and add more details to make it visually appealing.

Now, you have a 3D working model that showcases different types of triangles using a wheel and arrow design made from cardboard and color paper. This model can be a helpful visual aid to understand and differentiate between various types of triangles. By rotating the wheel, one can identify each triangle type and learn about their unique characteristics. It’s an interactive and creative way to explore the properties and classification of triangles.
