Carry the same change

Name what changes in the first pair, then apply it to the second pair.

Compare properties, not whole pictures

AB
Read the first pair from left to right: A becomes B.

A figure analogy has two pairs. Picture A changes into B. Apply the same change to C to find the missing picture D.

More

Check one property at a time: shape, number, fill and, for triangles, direction. Name both what changed and what stayed the same.

Here, three outline circles become three filled circles. Only the fill changed. The number and shape stayed the same.

Lesson help

Transfer the rule to the new picture; preserve every property the rule does not change.

AB
Read the first pair from left to right: A becomes B.

Transfer the action, not the final picture

The first pair changes outline to filled. Picture C has two outline squares, so D needs two filled squares.

Do not copy B's three circles. Apply the action to C's own shapes and count.

A fill change works both ways: filled becomes outline, and outline becomes filled. Keep every property that the first pair leaves unchanged.

ABCD
The same fill change works on circles in the first row and squares in the second.

Find the new change

This pair uses a new rule. A has three outline circles; B has four outline circles. C has two filled squares.

In this practice, count rules keep the count, add or subtract one or two, double it, or halve it. Which of these fits A to B?

Apply that count rule to C. Also check whether A to B changes the shape or fill.

ABCD?
A becomes B. Apply that same rule to C to choose D.

Try it

Which picture completes the second pair?

  1. Three filled squares
  2. Three outline squares
Show the answer

Three filled squares

A to B adds one shape and keeps the shape and fill unchanged. Adding one to C's two filled squares gives three filled squares.
