📐 Part 1: Identifying Polygons

1. What is a polygon? Tick the best definition:

A 3D shape with curved sides

A 2D shape with straight sides that is closed

Any shape with corners

A shape that has parallel lines

2. Which of these are polygons? Tick all that apply:

Triangle

Circle

Square

Pentagon

Oval

3. A polygon with 6 sides is called a:

Pentagon

Hexagon

Octagon

Quadrilateral

4. Complete the sentence: A polygon has the same number of sides as it has __________.

Angles

Vertices

Lines of symmetry

Both angles and vertices

🔍 Part 2: Polygon Properties

5. Look at a square. Which properties does it have? Tick all that apply:

4 equal sides

4 right angles

2 pairs of parallel sides

4 lines of symmetry

All sides are perpendicular to adjacent sides

6. What is the difference between a regular and irregular polygon?

7. Name three types of angles you might find in polygons:

a) _________________ angle (less than 90°)

b) _________________ angle (exactly 90°)

c) _________________ angle (greater than 90°)

8. Explain what parallel sides means:

✏️ Part 3: Classification Challenge

9. Draw and label an example of each polygon:

Triangle:

Quadrilateral:

Pentagon:

10. Look around your classroom or think about shapes in your environment. Name two real-life objects that are polygon shapes and identify what type of polygon they are:

Object 1: _________________ is a _________________

Object 2: _________________ is a _________________

11. Challenge: If a polygon has 8 sides, how many vertices does it have? How many angles? Explain your reasoning:
