### Process (How to do the activity)

Procedure:

1. The teacher can use this geogebra file to introduce parallelograms to students.
2. Move the vertices A or B or D and observe different parallelograms formed like square, rectangle and rhombus.
3. Bring their attention to measures of sides, angles and diagonals.
• Developmental Questions:
1. Can you identify the figure ?
2. How many sides does this figure have ?
3. What do we call a figure with 4 sides ?
4. Are all 4 sides equal ?
5. What are parallel lines ?
6. Identify the 2 sets of parallel lines.
7. Spell out the differences between the figures formed with respect to sides, angles and diagnols.
8. What common features do you observe in all figures/shapes formed ?

### Evaluation at the end of the activity

1. Are square, rectangle and rhombus parallelograms ?
2. What are parallelograms ?
3. How many pairs of parallel lines does a parallelogram have
4. Is kite a parallelogram ?
