This section manages the mind teasing problems of development of squares by the blend of a few sections by selecting them from a gathering of given choices (for the most part five in number). The following discussion will help us in solving of such kind of problems:

- Select a piece which contains a right point between two adjoining external edges.
- Attempt to fit another piece in its hallow spaces.
- If you can’t locate any such piece, select another piece having a right angle.
- Repeat the methodology with various arrangements of such pieces.
- At long last, with the two pieces fitting into each other, locate the third piece which fits into the other two chose ones, to get finish square.

Problems

A. B. C. D. E.

By observing clearly, figure A fits into figure C to form a complete square and also figure B fits into figure E to form a complete square as shown below:

Figure D doe not fit any of the alternative figure to form a complete square.

Therefore, figure D is the answer.

Figure D doe not fit any of the alternative figure to form a complete square.

Therefore, figure D is the answer.

**Model 2:** Choose three out of the following five alternative figures which together form one of the four options namely a, b, c, or d and when fitted together will form a complete equilateral triangle.

A.

a) ABC

b) BCD

c) ABD

d) ABE

Select the largest figure which contains at least one angle of 60 degrees.

Clearly, figure B is larger.

Now, figure C fits into it as shown below:

Atlast, figure D fits into the above combination to form a complete equilateral triangle as shown below:

Therefore, the figures B, C and D fit into each other to form a complete equilateral triangle.

Hence, option (b) is correct answer.

Clearly, figure B is larger.

Now, figure C fits into it as shown below:

Atlast, figure D fits into the above combination to form a complete equilateral triangle as shown below:

Therefore, the figures B, C and D fit into each other to form a complete equilateral triangle.

Hence, option (b) is correct answer.

**Model 3:** A set of five alternative figures A, B, C, D and E followed by a set of four alternatives a, b, c and d is provided. It is required to select the alternative which represents three out of the five alternative figures which when fitted into each other would form a complete square.

A.

a) ACD

b) CDE

c) BCD

d) ACE

Combination of figures B, C and D, the square will be formed as shown below:

Therefore, option (c) is correct answer.

Therefore, option (c) is correct answer.

**Model 4:** A set of five alternative figures A, B, C, D and E followed by a set of four alternatives a, b, c and d is provided. It is required to select the alternative which represents three out of the five alternative figures which when fitted into each other would form a complete square.

A.

a) ACD

b) ADE

c) ABE

d) ABD

Combining figures A, D and E, square is formed as shown below:

Therefore, option (b) is the correct answer.

Therefore, option (b) is the correct answer.

**Model 5:** Five alternative figures namely A, B, C, D and E are given. Frim the five figures, two pairs of figures are obtained such that each pair forms a complete square. Select the odd figure which does not fit into any of the other alternative figures to form a complete square.

A.

Figures A and E form a square.

Other pair is figure B and D, also form a square.

The odd figure which does not fit into any of the other alternative figures to form a complete square is figure C.

Hence, figure C is the correct answer.

Other pair is figure B and D, also form a square.

The odd figure which does not fit into any of the other alternative figures to form a complete square is figure C.

Hence, figure C is the correct answer.

**Model 6:** A figure X is given, followed by four other alternative figures marked A, B, C and D. It is required to select the one figure from the alternatives, which fits exactly into figure X to form a complete square.

X.

By observing, it is clear that figure D fits exactly into figure X to form a complete square as shown below:

Therefore, figure D is the correct answer.

Therefore, figure D is the correct answer.

**Model 7:** A figure X is given, followed by four other alternative figures marked A, B, C and D. It is required to select the one figure from the alternatives, which fits exactly into figure X to form a complete square.

X.

By observing, it is clear that figure B fits exactly into figure X to form a complete square as shown below:

Therefore, figure B is the correct answer.

Therefore, figure B is the correct answer.

**Model 8:** A figure X is given, followed by four other alternative figures marked A, B, C and D. It is required to select the one figure from the alternatives, which fits exactly into figure X to form a complete square.

X.

By observing, it is clear that figure D fits exactly into figure X to form a complete square as shown below:

Therefore, figure D is the correct answer.

Therefore, figure D is the correct answer.

**Model 9:** A figure X is given, followed by four other alternative figures marked A, B, C and D. It is required to select the one figure from the alternatives, which fits exactly into figure X to form a complete square.

X.

By observing, it is clear that figure C fits exactly into figure X to form a complete square as shown below:

Therefore, figure C is the correct answer.

Therefore, figure C is the correct answer.

**Model 10:** A figure X is given, followed by four other alternative figures marked A, B, C and D. It is required to select the one figure from the alternatives, which fits exactly into figure X to form a complete square.
