GMA Mirror Images and Embedded Figures 3 — Questions and Answers
Question 1: A shape has a dot at its top-left corner. After reflecting it in a vertical mirror, where is the dot?
- Top-left
- Bottom-left
- Top-right (Correct answer)
- Bottom-right
Correct answer: Top-right
Vertical reflection swaps left and right, moving the top-left dot to the top-right position.
Question 2: Which capital letter looks the same in BOTH a vertical and a horizontal mirror?
- A
- H (Correct answer)
- T
- D
Correct answer: H
The letter H has both left-right and top-bottom symmetry, so it appears identical in both types of mirror reflection.
Question 3: In an embedded figures test, you are shown a simple diamond shape and asked to find it inside a complex figure. The most effective strategy is to:
- Look for the exact proportions and orientation of the diamond (Correct answer)
- Search only along the edges of the complex figure
- Look for the largest shapes first
- Count all triangles in the figure first
Correct answer: Look for the exact proportions and orientation of the diamond
Matching exact proportions and orientation of the target shape helps identify it even when obscured by surrounding lines.
Question 4: A right-pointing triangle is reflected in a horizontal mirror. The reflected triangle points:
- Left
- Right (Correct answer)
- Up
- Down
Correct answer: Right
A horizontal mirror only flips the figure top-to-bottom; horizontal direction (right) remains unchanged.
Question 5: The number '81' is held up to a vertical mirror. What does the reflection read?
- 18
- 81 reversed (mirror-flipped digits) (Correct answer)
- 61
- 18 reversed
Correct answer: 81 reversed (mirror-flipped digits)
In a vertical mirror, the order of digits reverses AND each digit is individually flipped, giving mirror-flipped '18'.
Question 6: When looking for an embedded triangle in a complex shape, you notice the target triangle has a 60° apex angle. You should search the complex figure for internal angles of:
- 30°
- 60° (Correct answer)
- 90°
- 120°
Correct answer: 60°
The embedded shape retains the same angles as the original target, so you look for the identical 60° angle.
Question 7: A butterfly image is symmetric about a vertical axis. Its mirror image (vertical mirror) will look:
- Identical to the original (Correct answer)
- Flipped upside down
- Rotated 90°
- Like a different butterfly species
Correct answer: Identical to the original
Since the butterfly is already vertically symmetric, reflecting it in a vertical mirror produces an identical image.
A shape has a dot at its top-left corner.
After reflecting it in a vertical mirror, where is the dot?
