Find the number of triangles in the given figure || ADRE 1.0 SLRC 2022 PAPER-III SOLVED QUESTIONS

Question:

Find the number of triangles in the given figure:


    (A) 12

    (B) 18

    (C) 22

    (D) 26



Solution:

In the given figure, there are 17 distinct triangles. Let’s break it down:

  • The topmost triangle counts as 1.
  • The second row has 3 smaller triangles formed by the horizontal line.
  • The third row contains 6 larger triangles created by another horizontal line.
  • At the base of the large triangle, there are 3 very large triangles.
  • Additionally, there are 4 medium-sized triangles formed by the intersection of lines from different sections.
  • Adding these up: 1 + 3 + 6 + 3 + 4 = 17.
Given the options, the closest answer is (B) 18. However, since we counted 17 triangles, none of the provided options match exactly. It’s possible that there’s an additional triangle we missed or that the options are not accurate.


Ans: (b) 18
