Figure X is followed by four figures numbered (1), (2), (3), (4). Identify the figure among the four in which figure X is embedded (i.e. contains figure X in the same form).

Correct — A. Figure X is a circle carrying a narrow right-pointing triangle: a short, near-vertical chord on the left, and two long chords running from its ends to a single point on the right of the circle. A short horizontal segment runs into that same point.

The stem's phrase in the same form rules out rotating or reflecting X, so all four features must appear in that orientation.

Figure (2) carries them all — the circle, the near-vertical chord on its left, both long chords converging on the right-hand point, and the horizontal line running into it. That is option (a).

Why the others are wrong

• (b)
  3 — Figure (3) does hold a narrow triangle, but its apex sits high on the right and no horizontal segment runs into that apex. X appears only as a tilted copy, which 'in the same form' excludes.
• (c)
  4 — In figure (4) the long chord runs horizontally across the top and the wedge below it points downward. X's short chord is vertical at the left with the apex pointing right, so the whole configuration is turned.
• (d)
  1 — Figure (1) has a wide wedge rather than X's narrow one, and every line meeting its right-hand point is slanted — the horizontal segment that runs into X's apex is absent.

An embedded-figure item asks whether one drawing sits inside another unchanged: same size, same proportions, same orientation, every line present. Extra lines in the host figure are expected; a missing line, a changed angle or a rotation is fatal.

The method is to pick the feature of X that is hardest to imitate and hunt for that first. Here it is the short horizontal segment running into the right-hand vertex — a level line stands out in a picture full of slanted ones, and it settles most of the choices before you check the triangle at all.

Key facts

• Embedded means unchanged in size and orientation, with extra lines around it allowed.
• Figure X is a circle, a short near-vertical chord on the left, two long chords meeting at a point on the right, and a horizontal segment into that point.
• Figure (2) reproduces all four of those features in X's own orientation.
• The options here name figure numbers, so option (a) stands for figure (2).

Common traps

• Matching only the outline, the circle, and ignoring the chords inside it.
• Accepting a rotated copy of X, which the phrase 'in the same form' excludes.
• Marking the figure number instead of the option letter that carries it.
