types of angles working model – maths exhibition – diy – simple and easy steps | DIY pandit

Creating a working model to demonstrate different types of angles for a math exhibition using cardboard and paper can be a fun and educational project.

Here’s a simple and easy DIY (Do It Yourself) project that showcases various types of angles:

Materials Needed:

  1. Cardboard
  2. Colored paper
  3. Ruler
  4. Protractor
  5. Compass
  6. Pencil
  7. Scissors
  8. Glue or tape
  9. Markers
  10. Wooden dowels or straws

Steps to Create the Types of Angles Working Model:

Step 1: Prepare the Base:

  • Cut a large piece of cardboard to serve as the base for your working model.

Step 2: Create Angles Templates:

  • Draw and cut out templates for different types of angles using colored paper. Include templates for:
    • Acute angles
    • Obtuse angles
    • Right angles
    • Straight angles
    • Reflex angles
    • Full angles

Step 3: Label the Templates:

  • Label each template with the name of the corresponding angle type.

Step 4: Attach Templates to Dowels:

  • Glue or tape the angles templates onto wooden dowels or straws.

Step 5: Attach Dowels to the Base:

  • Attach the dowels or straws with the angle templates to the cardboard base. Place them in a way that allows for easy rotation.

Step 6: Protractor Display:

  • Attach a protractor to the base of the cardboard, ensuring it is securely fixed and easy to read.

Step 7: Display and Explain:

  • Set up your working model at the exhibition table.
  • Demonstrate each type of angle by rotating the corresponding dowel or straw. Use the protractor to measure and confirm the angle.

Step 8: Optional – Angle Facts:

  • Create small cards or labels to display interesting facts or properties about each type of angle.


  • During your exhibition, explain the characteristics of each angle type.
  • Discuss real-world examples and applications of different types of angles.

This working model provides a hands-on and visual representation of various types of angles, making it an engaging and interactive display for a math exhibition. It allows students and visitors to physically interact with the model, enhancing their understanding of angle concepts in mathematics.
