SSC CGL Previous Year Questions: Counting of Figures/Figure Formation & Analysis, Grouping of Figures - 1 - SSC CGL MCQ

By simple counting, we get that number of triangles in the given figure  = 34.

After counting the number of triangles in the given figure, we get that, total number of triangles = 18.

Number of squares in the given figure are 16.

According to figure,

The triangles are :
ΔAGD, ΔAGB, ΔADB, ΔACF, ΔABC, ΔADC,
ΔBGC, ΔBDC, ΔBDE, ΔDGC, ΔDHF, ΔDHC,
ΔDCF, ΔDEC, ΔDFE, ΔCHE, ΔCFE, ΔFHE
Thus, there are 18 triangles.

The Triangles are: ΔABG, ΔAGF, ΔABF, ΔABH, ΔAFH, ΔBGH, ΔBFH, ΔBFE,
ΔBFC, ΔBHC, ΔBEC, ΔCHI, ΔCHE, ΔCFE, ΔCID, ΔCED,  ΔDIE,
ΔDHE, ΔFHE, ΔEIH, ΔFGH and ΔDHC = 22 triangles.

Total number of triangles = 37.

The Triangles are : ABC, AKL, AKJ, BDK, BHK, KLM, KIM, KHG, FGE,
FHM, FHI, CDL, DEM, MIH, GDH, CHJ and KEI.
So, total triangles are 17.

The triangles are: ΔABC,  ΔABD,  ΔADC,  ΔAED,  ΔAFD,  ΔBEG, ΔBED,
ΔGED,  ΔDFC,  ΔFHC and ΔDFH.
∴ Total number of triangles = 11.

According to figure,

The triangles are: ΔAGD ; ΔAGB; ΔADB; ΔACF; ΔABC; ΔADC
ΔBGC; ΔBDC; ΔBDE; ΔDGC; ΔDHF; ΔDHC
ΔDCF; ΔDFC; ΔDFE; ΔCHE; ΔCFE; ΔFHE
Thus, there are 18 triangles.

The quadrilaterals are: ABFE and AECB Thus, there are 2 quadrilaterals.

The triangles are : ΔAIH ; ΔAIE; ΔEIB; ΔBFI;
ΔIHC; ΔIGC; ΔIGD; ΔDFI;
ΔIAB; ΔIBD; ΔICD; ΔIAC;
ΔBAC ; ΔACD; ΔBDC; ΔBDA;
ΔBLD;  ΔLDK; ΔKLJ; ΔJLB;
ΔJBK; ΔBDK; ΔDBJ; ΔDKJ
ΔADJ; ΔCBK.
Thus, there are 26 triangles.

ΔABD,  ΔADC,  ΔBDE,  ΔDEC,
ΔABC,  ΔEBC,  ΔACE,  ΔABE,
ΔBEF,  ΔFIG,  ΔCEH,  ΔHGK,
ΔFGE,  ΔEGH,  ΔGIL,  ΔILJ,
ΔGLK,  ΔLJK,  ΔGIJ,  ΔGKJ,
ΔGIK,  ΔIJK,  ΔBCH,  ΔIHK,
ΔBFC,  ΔFIK,  ΔFCK,  ΔHBI
Total Triangles = 28
