Core review

What to study

  • Track one distinctive corner, tab, or mark through each transformation.
  • A rotation preserves shape and handedness; a reflection reverses handedness.
  • Match tabs with corresponding gaps and eliminate impossible overlaps.

Five-question review

Try original assembling objects questions.

Attempt each question before opening the answer and explanation.

Question 1

An arrow points north. After a 90° clockwise rotation, which direction does it point?

  1. West
  2. East
  3. South
  4. North
Reveal answer and explanation

Correct answer: East

A quarter-turn clockwise from north points east.

Question 2

A square sheet is folded in half from left to right. A hole is punched through both layers near the folded edge. When opened, the holes will be:

  1. Mirror images across the fold
  2. In one corner only
  3. At right angles
  4. On top of each other at the outer edges
Reveal answer and explanation

Correct answer: Mirror images across the fold

Unfolding reflects the punched location across the fold line.

Question 3

A shape is made from three equal squares in a straight row. Which description matches a 90° rotation?

  1. Three squares in a vertical column
  2. Two squares only
  3. A triangle
  4. Three overlapping squares
Reveal answer and explanation

Correct answer: Three squares in a vertical column

Rotating a horizontal row by 90° produces a vertical column.

Question 4

A cube has red opposite blue and green opposite yellow. Which color cannot share an edge with red?

  1. Green
  2. Yellow
  3. Blue
  4. White
Reveal answer and explanation

Correct answer: Blue

Opposite faces do not share an edge, so blue cannot border red.

Question 5

A capital L is rotated 180°. Where will its long vertical stroke appear relative to its original position?

  1. Unchanged
  2. On the opposite side and inverted
  3. Horizontal only
  4. Removed
Reveal answer and explanation

Correct answer: On the opposite side and inverted

A half-turn moves every part to the opposite side and reverses its orientation.
