MASS Spatial Reasoning Principles 2 — Questions and Answers
Question 1: When a 2D net of a cube is folded, two faces that share an edge on the net will:
- Always end up opposite each other
- Be adjacent on the finished cube (Correct answer)
- Disappear into the interior
- Become the top and bottom only
Correct answer: Be adjacent on the finished cube
Faces sharing an edge on a net remain adjacent after folding.
Question 2: A figure is rotated 90° clockwise. A shape pointing up will now point:
- Down
- Left
- Right (Correct answer)
- Up still
Correct answer: Right
A 90° clockwise rotation turns an upward arrow to point right.
Question 3: Which transformation produces a mirror image of an object?
- Translation
- Rotation
- Reflection (Correct answer)
- Scaling
Correct answer: Reflection
Reflection flips an object across an axis to create a mirror image.
Question 4: Two gears mesh together. If the left gear turns clockwise, the right gear turns:
- Clockwise
- Counterclockwise (Correct answer)
- It stops
- Same speed, same direction
Correct answer: Counterclockwise
Meshed gears always rotate in opposite directions.
Question 5: An object viewed from directly above shows its:
- Front elevation
- Side profile
- Top (plan) view (Correct answer)
- Cross-section
Correct answer: Top (plan) view
Looking straight down gives the top or plan view.
Question 6: If a stack contains 3 layers of 4 cubes each, the total number of cubes is:
- 7
- 12 (Correct answer)
- 16
- 9
Correct answer: 12
Three layers of four cubes equal twelve cubes.
Question 7: A symmetrical shape folded along its line of symmetry will have halves that:
- Overlap exactly (Correct answer)
- Differ in size
- Rotate apart
- Form a new shape
Correct answer: Overlap exactly
A line of symmetry divides a shape into matching, overlapping halves.
