Question

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

Answer:

A. 1

The correct mirror image is 1.

1. Top Shaded Region: In the original figure, the black triangle at the top is on the right side. In the mirror image, it must flip to the left side (this eliminates option 4).

2. Horizontal Lines: The two horizontal lines on the middle-right side of the original figure must flip to the middle-left side (this eliminates option 2).

3. Bottom Shaded Region: In the original figure, the bottom-left corner is white, and the black shaded triangle is positioned internally next to the vertical line. In the mirror image, the bottom-right corner must remain white, with the black triangle reflecting to the inner right side.

   • Option 1 correctly keeps the corner white.

   • Option 3 incorrectly turns the entire bottom-right corner black.
