The image formed by a plane mirror is upright.

Answer

To solve the question, "The image formed by a plane mirror is upright," we can follow these steps:

### Step 1: Understand the characteristics of a plane mirror
A plane mirror is a flat reflective surface that reflects light according to the law of reflection. When light rays hit the mirror, they bounce back at the same angle they hit the surface.

**Hint:** Remember that the law of reflection states that the angle of incidence is equal to the angle of reflection.

### Step 2: Identify the type of image formed by a plane mirror
When an object is placed in front of a plane mirror, the image formed has specific characteristics:
- The image is virtual, meaning it cannot be projected on a screen.
- The image is upright, meaning it has the same orientation as the object.
- The image is of the same size as the object.

**Hint:** Think about how you see your reflection in a mirror. Does it look the same way you do?

### Step 3: Visualize the image formation
If we place an object in front of a plane mirror, the rays of light from the object reflect off the mirror and appear to come from a point behind the mirror. This point is where the virtual image is located. The image appears to be the same distance behind the mirror as the object is in front of it.

**Hint:** Imagine standing in front of a mirror and looking at your reflection. Your reflection appears to be behind the mirror.

### Step 4: Conclude the statement
Based on the characteristics of the image formed by a plane mirror, we can conclude that the statement "The image formed by a plane mirror is upright" is true. The image is indeed upright, virtual, and of the same size as the object.

**Hint:** Reflect on the fact that mirrors create images that maintain the same orientation as the original object.

### Final Answer:
True, the image formed by a plane mirror is upright.
