MASS Spatial Reasoning Principles 3 — Questions and Answers
Question 1: When unfolding a folded paper that was punched once while folded in half, the holes will appear:
- As a single hole
- Symmetrically on both halves (Correct answer)
- Only on the fold line
- Randomly placed
Correct answer: Symmetrically on both halves
Punching through folded paper creates mirror-image holes on each half.
Question 2: A 3D object's side view is also called its:
- Plan view
- Elevation (Correct answer)
- Isometric view
- Section view
Correct answer: Elevation
A view from the side is called an elevation.
Question 3: Rotating a shape 180° is equivalent to:
- No change
- Two 90° turns in the same direction (Correct answer)
- A single reflection
- A translation
Correct answer: Two 90° turns in the same direction
A 180° rotation equals two consecutive 90° turns the same way.
Question 4: Which pair of cube faces can NEVER be adjacent on a folded cube?
- Faces sharing a net edge
- Opposite faces (Correct answer)
- Faces meeting at a corner
- Faces in an L-shape
Correct answer: Opposite faces
Opposite faces never touch, so they cannot be adjacent.
Question 5: A right-handed glove reflected in a mirror appears as a:
- Right-handed glove
- Left-handed glove (Correct answer)
- Both hands
- No hand
Correct answer: Left-handed glove
Mirror reflection reverses handedness, turning right into left.
Question 6: In a series of three meshed gears, the first and third gears turn:
- Opposite directions
- The same direction (Correct answer)
- Both stop
- At random
Correct answer: The same direction
An odd number of meshed gears makes the first and last turn the same way.
Question 7: An isometric drawing shows an object with:
- Only one face
- Three faces at equal angles (Correct answer)
- A flat top view
- A cut interior
Correct answer: Three faces at equal angles
Isometric views display three faces with equal 120° angles.
