Show Answer Key & Explanations Step-by-step solution for: Lines of Symmetry Worksheets | Worsheets library
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 common geometry problems like this, I’ll walk you through how to draw lines of symmetry for typical shapes found on such a worksheet.

The goal is to draw a line (or lines) that divides each shape into two mirror-image halves — meaning one side is a reflection of the other across the line.

Let’s go through each shape typically found on such worksheets and explain where to draw the line(s) of symmetry:

---

1. Square


- Has 4 lines of symmetry:
- 2 diagonals (from corner to corner)
- 1 vertical line through the middle
- 1 horizontal line through the middle
- 📌 Draw any one of these lines (usually vertical or horizontal is expected).

---

2. Circle with a rectangle (like a "T" shape or "plus" shape)


This looks like a rectangle with a circle on top and bottom, forming a vertical bar with circles.
- This shape has vertical symmetry only.
- Draw a vertical line down the center — it splits the shape into two equal mirrored halves.
- No horizontal symmetry because the top and bottom are circles, but the rectangle may not be symmetric if it's uneven.

> Note: If the shape is a cross (plus sign) made of squares or rectangles, it has 4 lines of symmetry: vertical, horizontal, and both diagonals.

3. Semicircle (half-circle)


- Only one line of symmetry: the diameter line (straight edge).
- Draw a vertical line through the center of the curved part — from the midpoint of the straight edge to the curved arc.
- The two sides will reflect across this line.

---

4. Arrow-like shape (pointing left/right)


This is likely a triangle with a tail, like an arrowhead.
- Usually has one line of symmetry: along the center axis from the tip to the base.
- Draw a vertical line down the middle of the arrow.

---

5. House shape (triangle on top of a rectangle)


- One vertical line of symmetry through the center.
- Draw a line from the peak of the triangle down through the center of the rectangle.
- The two sides should be mirror images.

---

6. Star (likely a regular 5-pointed star)


- A regular 5-pointed star has 5 lines of symmetry.
- Each line goes from a point to the midpoint of the opposite side.
- You can draw one of them — usually from a tip to the center.
- The line passes through the center and splits the star into two matching halves.

---

7. Triangle (equilateral or isosceles)


- If it's equilateral, it has 3 lines of symmetry — from each vertex to the midpoint of the opposite side.
- If it's isosceles, it has 1 line of symmetry — from the apex to the base midpoint.
- Draw the vertical line down the center.

---

8. Shape resembling a "house" with a pointed roof and a flat base (but wider at the top)


This might be a trapezoid with a triangular top or a chevron-like shape.
- Likely has one vertical line of symmetry through the center.
- Draw a vertical line down the middle so the left and right sides match.

---

General Tips:


- 🔍 Look for mirror-image halves.
- 🔁 Try folding the shape mentally — where would it fold perfectly?
- ⚠️ Some shapes (like circles, squares, stars) have multiple lines; others (like irregular shapes) may have none.
- 💡 Use a ruler to draw clean, straight lines.

Final Answer Summary (What to Draw):


For each shape, draw:
1. Square → Vertical or horizontal line through center.
2. Cross/Plus Shape → Vertical or horizontal line through center.
3. Semicircle → Vertical line through center (along diameter).
4. Arrow → Vertical line down the center.
5. House → Vertical line through the peak and center of rectangle.
6. Star → Line from a point to the center (one of five possible).
7. Triangle → Vertical line from tip to base midpoint.
8. Chevron/House-like shape → Vertical line down the center.

All these lines divide the shape into two parts that are reflections of each other.
