Mirror Image Reflection Solution

This solution explains how to determine the mirror image of the provided figure when a mirror is placed on the shaded line.

Understanding Horizontal Mirror Reflections

A mirror placed on a horizontal line reflects the object vertically. This means:

• The top part of the object appears at the bottom in the image.
• The bottom part of the object appears at the top in the image.
• The left and right sides remain in the same position relative to the mirror line.

Analyzing the Figure and Mirror Placement

1. Identify Mirror Line: The shaded line is the mirror, positioned horizontally across the center of the figure.

2. Analyze Original Figure: Note the shapes and positions of elements above and below the mirror line.

3. Apply Reflection: Visualize flipping the figure vertically across the horizontal mirror line.

• The elements originally above the mirror will appear inverted below the mirror.
• The elements originally below the mirror will appear inverted above the mirror.
• The relative positions and orientations must be accurately inverted.

Evaluating the Options

Compare the expected vertically flipped image with the options provided:

• Option 1 incorrectly shows the reflection.
• Option 2 is not the correct vertical reflection.
• Option 3 accurately represents the mirror image. It shows a complete vertical flip: the top portion is inverted and moved below the mirror line, and the bottom portion is inverted and moved above the mirror line.
• Option 4 does not match the required vertical inversion.

Based on the vertical flip across the horizontal mirror line, Option 3 is the correct mirror image.
