The task is to draw the line(s) of symmetry for each of the given shapes. A
line of symmetry is a line that divides a shape into two identical halves, such that one half is the mirror image of the other.
Let's analyze and solve this step by step for each shape:
---
1. Equilateral Triangle
- An equilateral triangle has
three lines of symmetry.
- Each line passes through one vertex and the midpoint of the opposite side.
- Draw three lines: one from each vertex to the midpoint of the opposite side.
---
2. Heart Shape
- The heart shape has
one line of symmetry.
- This line runs vertically down the middle of the heart, dividing it into two identical halves.
- Draw a vertical line through the center.
---
3. Oval
- An oval (or ellipse) has
two lines of symmetry.
- One line runs horizontally through the center, and the other runs vertically through the center.
- Draw both a horizontal and a vertical line through the center.
---
4. Irregular Pentagon
- This pentagon appears to be irregular, so it likely has
no lines of symmetry unless specified otherwise.
- If it were regular, it would have five lines of symmetry, but since it is irregular, we assume it has none.
- Do not draw any lines.
---
5. Letter "E"
- The letter "E" has
one line of symmetry.
- This line runs vertically down the middle of the "E," dividing it into two identical halves.
- Draw a vertical line through the center.
---
6. Tulip Flower
- The tulip flower has
one line of symmetry.
- This line runs vertically down the middle of the flower, dividing it into two identical halves.
- Draw a vertical line through the center.
---
7. Car
- The car has
one line of symmetry.
- This line runs vertically down the middle of the car, dividing it into two identical halves.
- Draw a vertical line through the center.
---
8. Vase
- The vase has
one line of symmetry.
- This line runs vertically down the middle of the vase, dividing it into two identical halves.
- Draw a vertical line through the center.
---
9. Stick Figure Person
- The stick figure person has
one line of symmetry.
- This line runs vertically down the middle of the figure, dividing it into two identical halves.
- Draw a vertical line through the center.

Final Answer:
For each shape, draw the appropriate lines of symmetry as described above. Here is a summary:
1.
Equilateral Triangle: Draw 3 lines (through each vertex to the midpoint of the opposite side).
2.
Heart: Draw 1 vertical line.
3.
Oval: Draw 2 lines (horizontal and vertical).
4.
Irregular Pentagon: Draw 0 lines (none).
5.
Letter "E": Draw 1 vertical line.
6.
Tulip Flower: Draw 1 vertical line.
7.
Car: Draw 1 vertical line.
8.
Vase: Draw 1 vertical line.
9.
Stick Figure Person: Draw 1 vertical line.
$$
\boxed{\text{Draw the lines as described above for each shape.}}
