Creating a **working project on types of angles** in both **clock** and **flower formats** using paper, cardboard, and push pins is a fun and interactive way to understand angle concepts.

Here’s a step-by-step guide for each format:

### Materials Needed:

**Cardboard**(for the clock face)**Paper**(for making clock hands and labeling)**Push pin**(for attaching movable clock hands)**Markers**(for drawing the clock face and labeling)**Scissors****Ruler and compass****Glue or tape**

#### Video Steps to Make the Model:

##### 1. **Create the Clock Face:**

- Cut out a
**circle**from a large piece of cardboard (around 12 inches in diameter). - Use a
**ruler and compass**to draw the clock markings on the circle. - Divide the circle into 12 equal sections to represent the hours on a regular clock.
- Label the hours from 1 to 12 around the edge of the circle.

##### 2. **Make the Clock Hands:**

- Cut out two
**clock hands**from paper: one for the**minute hand**and one for the**hour hand**. - These hands will represent the angles, and you can make them adjustable using a push pin.

##### 3. **Attach the Clock Hands:**

- Use a
**push pin**to attach the two hands to the center of the clock face, making sure they can rotate freely.

##### 4. **Show Different Types of Angles:**

- Now, by rotating the clock hands, you can demonstrate different angles:
**Right Angle (90°)**: When the hands are at 3 and 12 or 9 and 12.**Acute Angle (<90°)**: When the hands form a narrow angle, like 1 and 12.**Obtuse Angle (>90° and <180°)**: When the hands are wider, like 10 and 12.**Straight Angle (180°)**: When the hands are exactly opposite, like 12 and 6.**Reflex Angle (>180° and <360°)**: When the hands go beyond 180°, such as 2 and 8.**Full Angle (360°)**: When the hands make a complete turn.

##### 5. **Label the Angles:**

- Use colored paper or markers to create small labels for each angle type. Attach these labels to the clock face with arrows pointing to the angles formed by the hands.
