ASVAB · Fitting Parts Together

You need to identify which of four answer shapes, when combined with a given irregular polygon, will form a rectangle. The given polygon has one straight edge on the right side. Which property must the answer shape have on its left side?

Correct answer

An identical straight edge — the contact edges must be complementary (mirror images) to produce a seamless fit

A A curved edge
B An identical straight edge — the contact edges must be complementary (mirror images) to produce a seamless fit
C A jagged edge
D Any edge, since the rectangle shape determines everything

Why this is the answer

The contact edge of the answer shape must be the mirror image of the given polygon's contact edge. If the given shape has a straight right edge, the answer shape needs a straight left edge. If the given shape has a convex curve, the answer needs a concave curve of matching radius. This mirror-edge principle is the core logic of all fitting-parts questions.

An Assembling Objects fitting-parts question shows several disassembled pieces (like puzzle pieces) and four answer figures showing one possible assembled shape each. Your job is to find the answer where:

In a fitting-parts question, if one of the disassembled pieces is an L-shape (like a right-angle bracket), what changes are allowed when fitting it into the assembled answer?

If a fitting-parts question shows you 4 pieces and one of the answer choices shows an assembled figure made of only 3 visible regions, what should you conclude?

In an ASVAB Assembling Objects 'part fitting' question, you see an irregular polygon and four answer choices showing how two shapes could fit together. The correct answer shows them fitting without overlap or gap. What mental strategy helps most?
