To solve this worksheet, we need to check each shape against the rules for being a polygon.
Rules for a Polygon:
1. It must be a
closed shape (no gaps in the outline).
2. It must be made of
straight lines only (no curves).
3. The lines cannot cross each other.
Let's look at each shape one by one:
Row 1:
1.
Hexagon: It is closed and has straight sides. ->
Polygon
2.
Trapezoid: It is closed and has straight sides. ->
Polygon
3.
Octagon: It is closed and has straight sides. ->
Polygon
Row 2:
4.
Triangle: It is closed and has straight sides. ->
Polygon
5.
Heart: It has curved lines on the top. Polygons cannot have curves. ->
NONE
6.
Pentagon: It is closed and has straight sides. ->
Polygon
Row 3:
7.
Irregular Hexagon: It is closed and has straight sides. ->
Polygon
8.
Rectangle: It is closed and has straight sides. ->
Polygon
9.
Irregular Quadrilateral: It is closed and has straight sides. ->
Polygon
Final Answer:
1. Polygon
2. Polygon
3. Polygon
4. Polygon
5. NONE
6. Polygon
7. Polygon
8. Polygon
9. Polygon
