ASVAB · Fitting Parts Together

When pieces in a puzzle problem have curved and straight edges, the correct assembly will:

Correct answer

Match curved edges to curved edges and straight edges to straight edges where they connect, forming a seamless complete shape

  1. A Only use straight edges
  2. B Discard curved pieces
  3. C Match curved edges to curved edges and straight edges to straight edges where they connect, forming a seamless complete shape
  4. D Mix them randomly

Why this is the answer

The correct assembly MATCHES edges appropriately — a curved edge of one piece fits against the corresponding curved edge of an adjacent piece, and straight edges align with straight edges — forming a SEAMLESS complete shape without gaps or overlaps. ASVAB Assembling Objects tests precise edge matching. Curved and straight edges are strong clues: a convex curve on one piece fits a concave curve on its neighbor; straight edges line up flush. Use these edge features to determine how pieces connect and to eliminate answers where edges don't actually match. Edge shape compatibility is a key fitting clue.

About this topic: Fitting Parts Together

Fitting-parts items show a set of pieces and ask which finished figure they form, like a jigsaw. Count the pieces, match distinctive edges, and eliminate answers that use a shape not in the set or change a shape's size. This is one of 14 Assembling Objects questions on fitting parts together, each with a full explanation on a single study page.
