Is there any short tricks for these type of problems? |

Azhar said: (Jun 14, 2013) | |

By using count only, we can find out the answers for this type of problems. |

Sri said: (Dec 25, 2013) | |

Is there any shortcut for counting number of triangle? |

Midhun Kumar said: (Dec 28, 2013) | |

No short cuts are available till now, we have to solve by ourselves. |

Prakash said: (Apr 16, 2014) | |

Is there any shortcut for these problems to solve? |

Prathap said: (Apr 30, 2014) | |

These kind of problems are a kind of dynamic ones hence dealing with formulae can't happen at ease. |

Dharshan said: (May 17, 2014) | |

Is there any formulas to calculate the problem? |

Zarish said: (Jul 24, 2014) | |

What is meant by components ? |

Swetha said: (Oct 19, 2014) | |

@Zarish Components refers to sides of the triangle. |

Is there any trick to solve this type of problems. |

Balaganesh Akasapu said: (May 14, 2015) | |

Fortunately yes, we can use the concept of combinations to crack the problem with no time. |

Revanth said: (May 28, 2015) | |

I need some shortcut way to solve this. Can anyone suggest me? |

Pawan said: (Jun 30, 2015) | |

Tell the time saving trick, the above process is time consuming. |

Shashikant Kumar said: (Aug 15, 2015) | |

The figure shows a triangle with many lines. If the number of internal lines from vertex E=4, and the number of internal lines parallel to base is 2, then [4 X 2 X (2+1)]/2 = 12 and then add the rest small triangle at side and the main large triangle, you will get 18. |

Karthik said: (Apr 26, 2016) | |

How this way is possible? No of nodes + 2 * No of inner nodes. Ca anyone explain it? |

Jaisun said: (Jun 5, 2016) | |

Will the formula is given above be applicable for all triangle based sums? Please tell me, I need help. |

Jitesh said: (Jul 17, 2016) | |

Please anyone tell me the Short trick for solving the problem. |

Rupesh Singh said: (Jul 28, 2016) | |

Is there any other way to solve it easily. |

Pratham Verma said: (Dec 25, 2016) | |

Count by nodes 2Rupesh. |

Himanshu Tomar said: (Feb 2, 2017) | |

Is there any short trick to find the answer? |

The simplest triangles are AHB, GHI, BJC, GFE, GIE, IJE, CEJ and CDE which equals 8 in number. The triangles composed of two components each are HEG, BEC, HBE, JGE and ICE = 5 in number. The triangles composed of three components each are FHE, GCE and BED which are 3 in number. There is only one triangle i.e. AGC composed of four components. There is only one triangle i.e. AFD composed of nine components(sides of triangles. Thus, there are 8 + 5 + 3 + 1 + 1 = 18 triangles in the given figure. |

Mansi Sahu said: (Apr 14, 2018) | |

I don't understand the proper meaning of components, please anybody can explain me clearly? |

Akter Ali said: (Jun 30, 2018) | |

The simple triangle means forming with 3 letters. Two components forming with 4 letters. Three components forming with 5 letters. |

Ritika said: (Aug 17, 2018) | |

I don't think so, that two components forming with 4 letters as HBE &BEC both are two components triangle but HBE made with 5 letters and BEC made with 4 letters. |

Sharad Bhatta said: (Sep 14, 2018) | |

I don't understand the concept of the triangle components. Please, anybody, give me some ideas. |

Rit said: (Dec 15, 2019) | |

Total no nodes (8) + 2 * (5) inner nodes (h, b, g, c, e) = 18. |

JIYA said: (Oct 9, 2020) | |

Please anyone tell me the correct way to solve this. |
