Solve Mirror and Water Images

Short Tricks to Solve Mirror and Water Images  Questions in Reasoning

Mirror Images Short Tricks

The figure obtained by putting a mirror in front of the real image is known as mirror image or we can say that the reflection of an object into the mirror is called its mirror image.

Let us consider an example

From the above figure, it is clear that in a mirror image top and bottom of an image does not change but LHS(Left Hand side) of a real image becomes RHS(Right Hand Side) in mirror image and RHS is real image become LHS in mirror image. So, it can be concluded that the mirror image is the lateral inversion of real image.
Now, look at the following figures:

Take a mirror and place it along the vertical dotted line running through the middle of this shape. You will see that the half figure on the left together with its image in the mirror on the right gives the complete figure of the heart.

So, we can say that on combining the original and mirror image together, they form a symmetry.

How to solve Water image questions

Water Images in non verbal reasoning is same as Mirror Images method. basically Water image is just a reflection where top and bottom part of the images changed where left and right side of image remain same. In Mirror image left side and right side changed vice-versa where top and bottom remain same. See below example to understand in brief.

see little DOG running on water where his legs reflecting first and head reflecting last both right side and left side remains unchanged.

Analytical Reasoning Question

Analytical Reasoning Question  Figures and answers : Non Verbal

1. Find the number of triangles in the given figure.

 

A.) 18
B.) 26
C.) 21
D.) 24

Answer: Option 'C' 

The figure may be labelled as shown.

simplest triangles are EFH, BIC, GHJ, GIJ, EKD and CKD i.e. 6 in number.

triangles composed of two components each are ABJ, AFJ, GCK, GEK, CED arid GHI that is 6 in number.

triangles composed of three components each are GCD, GED, DJB and DJF i.e. 4 in number.

triangles composed of four components each are ABF and GCE i.e. 2 in number.

triangles composed of five components each are ABD and AFD i.e. 2 in number.

There is only one triangle 

That is FBD composed of six components.

Total number of triangles in the pic = 6 + 6 + 4 + 2 + 2 + 1 = 21.

2. Find the number of triangles in the given figure.

 

A.) 4
B.) 5
C.) 7
D.) 6

Answer: Option 'B'

The figure may be labelled as shown.

The simplest triangles are ADE, BDF, DEF and EFC that is 4 in number.

There is only one triangle ABC composed of 4 components.

there are 4+1 = 5 triangles in the given figure.

3. Find the number of triangles in the given figure.

 

A.) 34
B.) 36
C.) 38
D.) 40

Answer: Option 'B'

The figure may be labelled as shown.

Simplest triangles are AML, LRK, KWD, DWJ, JXI, IYC, CYH, HTG, GOB, BOF, FNE and EMA that is 12 in number.

The triangles composed of 2 components each are AEL, KDJ, HIC and FBG that is 4 in number.

The triangles composed of 3 components each are APF, EQB, BQH, GVC, CVJ, IUD, DUL and KPA that is 8 in number.

The triangles composed of 6 components each are ASB, BSG, CSD, DSA, AKF, EBH, GGJ and IDL that is 8 in number.

The triangles composed of twelve components each are ADB, ABC, BCD and CDA that is 4 in number.

Total number of triangles in the fig = 12 + 4 + 8 + 8 + 4 = 36.

4. Find the number of triangles in the given figure.

 

A.) 25
B.) 27
C.) 33
D.) 38

Answer: Option 'B'

The figure may be labelled as shown.

Simplest triangles are GLK, DJM, HMN, QRE, IRA, DLJ, IPA and FPO that is 8 in number.

The triangles having 2 components each are BDO, CDQ, DLM, PRA, KFI, HJI, NEI, GJI, DKI and DNI that is 10 in number.

The triangles having 4 components each are DIE, DFI, DOA, DQA andGHI that is 5 in number.

The triangles having 6 components each are DCA and DBA that is 2 in number.

DEF is the only triangle having 8 components.

ABC is the only triangle having 12 components.

Thus, there are 8+10+ 5 + 2+1 + 1 = 27 triangles in the fig.
