MASS Assembling Objects 2 — Questions and Answers
Question 1: In a connection problem, two shapes each have a labeled point and a line connects those points. What must the correct answer show?
- The line attached at the exact labeled points on each shape (Correct answer)
- The two shapes overlapping each other
- The shapes rotated but with no connecting line
- Both shapes flipped into mirror images
Correct answer: The line attached at the exact labeled points on each shape
A connection answer must join the line endpoints to the precise labeled dots on each piece.
Question 2: When the same object is rotated in the answer choices, which feature stays unchanged?
- Its overall size and shape (Correct answer)
- Its color
- The number of dots added
- Its position on the page only
Correct answer: Its overall size and shape
Rotation preserves size and shape; only orientation changes.
Question 3: A puzzle shows five separate pieces. The correct assembled answer must use:
- All five pieces with none left over and none added (Correct answer)
- Only the largest four pieces
- Any pieces that fit, ignoring extras
- Three pieces plus one new shape
Correct answer: All five pieces with none left over and none added
Every given piece must appear exactly once in the assembled figure.
Question 4: How can you quickly eliminate a wrong assembly answer?
- Spot a piece that is the wrong size or a mirror image (Correct answer)
- Pick the most colorful option
- Choose the option with the most pieces
- Select whichever looks symmetrical
Correct answer: Spot a piece that is the wrong size or a mirror image
Mismatched sizes or flipped (mirrored) pieces signal an incorrect answer.
Question 5: In a connection question, a dot sits at the corner of a triangle. The connecting line must:
- Touch that exact corner (Correct answer)
- Touch the middle of the longest side
- Touch any corner of the triangle
- Float near the triangle without touching
Correct answer: Touch that exact corner
The line must attach at the specifically labeled corner, not just any corner.
Question 6: Two pieces in a shape puzzle have matching slanted edges. What does this suggest?
- Those edges likely join together in the assembly (Correct answer)
- The pieces cannot be used together
- One piece must be discarded
- The edges must be flipped to match
Correct answer: Those edges likely join together in the assembly
Matching edge lengths and angles indicate where pieces connect.
Question 7: A correct mirror-image trap answer is wrong because:
- A flipped piece is not the same as a rotated piece (Correct answer)
- It uses too few pieces
- It is rotated too far
- It changes the line color
Correct answer: A flipped piece is not the same as a rotated piece
Mirroring (flipping) a piece creates a different shape that cannot be made by rotation alone.
