NNAT3 Spatial Reasoning 3 — Questions and Answers
Question 1: A grid shows a 3×3 pattern of dots. Which arrangement has rotational symmetry of order 4?
- One dot at each corner
- Dots only along the top row
- A single dot in the center (Correct answer)
- Dots only in the middle column
Correct answer: A single dot in the center
A single dot at the center looks identical after any rotation, giving it order-4 rotational symmetry.
Question 2: A rectangle is rotated 180° about its center. Which statement is true?
- It looks different
- It looks the same (Correct answer)
- It becomes a square
- Its area doubles
Correct answer: It looks the same
A rectangle has 180° rotational symmetry, so it looks the same after a half-turn.
Question 3: Blocks are stacked as follows: 3 on the bottom row, 2 in the middle, 1 on top — all centered. How many blocks are there in total?
- 5
- 6 (Correct answer)
- 7
- 8
Correct answer: 6
3 + 2 + 1 = 6 blocks total.
Question 4: A piece is cut from the bottom-left corner of a square. Which shape best describes what remains?
- Square
- Pentagon (Correct answer)
- Triangle
- Hexagon
Correct answer: Pentagon
Removing one corner from a square leaves a shape with 5 sides — a pentagon.
Question 5: In a figure matrix, the top-left cell has a large dark circle and the top-right cell has a small dark circle. The bottom-left cell has a large white circle. What belongs in the bottom-right cell?
- Large dark circle
- Small white circle (Correct answer)
- Large white circle
- Small dark circle
Correct answer: Small white circle
The rule reduces size from large to small across columns, and the shading stays the same in each row (white row stays white).
Question 6: A flat net is folded into a 3-D shape. The net has 6 identical squares arranged in a cross shape. What solid does it form?
- Rectangular prism
- Cube (Correct answer)
- Pyramid
- Triangular prism
Correct answer: Cube
A cross-shaped net of 6 equal squares folds into a cube.
Question 7: Look at the sequence: ▲ ▲▲ ▲▲▲ __. What comes next?
- ▲▲
- ▲▲▲▲ (Correct answer)
- ▲▲▲▲▲
- ▲
Correct answer: ▲▲▲▲
Each term adds one triangle, so after three triangles comes four triangles.
