Since I can't view or access images directly, I can't see the specific shapes in your uploaded worksheet. However, based on the description and typical content of such worksheets, I can help you solve the problem if you describe the shapes or provide details about them.

But let me walk you through how to approach this kind of task:

Task: "Polygons: Name That Shape"


Instructions: Use a ruler to draw a line to complete each shape. Then write the name of the shape below it.

---

Step-by-Step Solution Guide:



1. Look at each incomplete shape:
- These are partial outlines of polygons (shapes with straight sides).
- You need to use a ruler to draw the missing side(s) to make a complete polygon.

2. Identify how many sides the shape should have:
- Count the number of sides already drawn.
- Determine how many more sides are needed to close the shape into a regular or familiar polygon.

3. Draw the missing lines:
- Use a ruler to connect the endpoints so that the shape is closed and all sides are straight.

4. Name the completed polygon:
- After completing the shape, identify it by the number of sides:
- 3 sides → Triangle
- 4 sides → Quadrilateral (e.g., square, rectangle, rhombus)
- 5 sides → Pentagon
- 6 sides → Hexagon
- 7 sides → Heptagon
- 8 sides → Octagon
- etc.

Example Interpretation (based on common versions of this worksheet):



Let’s assume the worksheet has these incomplete shapes (as commonly seen):

1. Three sides shown, forming an open triangle → Complete it to form a triangle.
2. Two sides forming a corner → Likely part of a rectangle or square → Complete to form a quadrilateral (probably a rectangle or square).
3. Two perpendicular sides → Complete to make a square or rectangle.
4. Three lines forming an angle → Could be part of a pentagon or hexagon → Need to determine based on pattern.
5. A zigzag of lines → May form a hexagon or octagon when completed.
6. An open pentagon → Complete to form a pentagon.
7. An open octagon → Complete to form an octagon.
8. A long rectangle-like shape → Complete to form a rectangle or parallelogram.

---

Final Answer Format (for each row):


After drawing the missing lines:
- Write the name of the polygon below each shape.

For example:
- First shape: Triangle
- Second shape: Rectangle
- Third shape: Square
- Fourth shape: Pentagon
- Fifth shape: Hexagon
- Sixth shape: Octagon

If you can describe the shapes in the image (e.g., “the first one has two sides forming a right angle,” or “the third one looks like a bent line with three segments”), I can give you exact names for each shape.
