Keyhole

• Common Strategies– Top/Front/End Method

InstructionsThis visualization test consists of a number of items. A three-

dimensional object is shown at the left. This is followed by outlines of five apertures of openings.

In each item the task is exactly the same. First, you are to imagine how the object looks from all directions. Then pick from the five apertures outlines, the opening through which the object could pass.

Instructions cont.Here are the rules:1. Prior to passing through the aperture, the irregular solid object may be

turned in any direction. It may be started through the aperture on a side not shown.

2. Once the object started through the aperture, it may not be twisted or turned. It must pass completely through the opening. The opening is always the exact shape of the appropriate external outline of the object.

3. Both objects and apertures are drawn to the same scale. Thurs, it is possible for an opening to be the correct shape, but too small for the object. In all cases, however, differences are large enough to judge by eye.

4. There are no irregularities in any hidden portion of the object. However, if the figure has symmetric indentations, the hidden portion is symmetric with the part shown.

5. Fore each object there is only one correct aperture.

Top/Front/End

• Common Strategies– Line Counting Method

InstructionsThe pictures that follow are top, front, and end views of various solid

objects. The views are without perspective. That is, the points in the viewed surface are viewed along parallel lines of vision. The projection looking down on it is shown in the upper left hand corer.

In the problems that follow, two views will be shown with four alternatives to complete the set. Hidden lines are shown as dashed.

Hole Punches

• Common Strategies– Tic-Tac-Toe Method

InstructionsA flat square of paper is folded one or more times. The broken lines

indicate the original position of the paper. The solid lines indicate the position of the folded paper. The paper is never turned or twisted. The folded paper always remains within the edges of the original square. There may be from one to three folds in each item. After the last fold a hole is punched in the paper. Your task is to mentally unfold the paper and determine the position of the holes in the original square.

Cube Counting

• Common Strategies– Cube Counting Method

InstructionsEach figure has been made by cementing together cubes of the same

size. After being cemented each group was painted on all sides EXCEPT FOR THE BOTTOM ON WHICH IT IS RESTING. The only hidden cubes are those required to support other cubes.

You are to examine each figure closely to determine how many cubes have how many of their sides painted.

Pattern Folding

• Common Strategies– Shape Matching Method– Color Matching Method

InstructionsA flat pattern will be presented. This pattern is to be folded into

a three-dimensional figure. The correct figure is one of the four given at the right of the pattern. There is only one correct figure in each set. The outside of the pattern is what is seen at the left.
