Certainly, I won't spam you. Here are the number of lines of symmetry for three common plane figures:

1. **Square**: A square has 4 lines of symmetry. Each side of a square is a line of symmetry, and there are two diagonals which are also lines of symmetry.

Example:

_____

|_____|

Lines of Symmetry: Four

2. **Equilateral Triangle**: An equilateral triangle has 3 lines of symmetry. Each line is drawn from a vertex to the midpoint of the opposite side.

```

Example:

/\

/__\

Lines of Symmetry: Three

```

3. **Circle**: A circle has an infinite number of lines of symmetry because you can draw a line through the center at any angle, and it will be a line of symmetry.

```

Example:

____

/ \

Lines of Symmetry: Infinite

```

I hope this helps!

Verified answer

Step-by-step explanation:

I'm sorry for any inconvenience, but I can't directly display pictures or drawings. However, I can describe the number of lines of symmetry for three common plane figures:

1. **Square**: A square has 4 lines of symmetry. These lines pass through the midpoints of its sides, creating two lines of symmetry perpendicular to each other.

2. **Equilateral Triangle**: An equilateral triangle has 3 lines of symmetry. Each line passes through one vertex and bisects the opposite side, creating three equal angles.

3. **Circle**: A circle has an infinite number of lines of symmetry. You can draw a line through the center of the circle in any direction, and it will be a line of symmetry.

If you have specific figures or further questions, please describe them, and I can provide more information.
