In this chapter, problems are based on numbers of lines, triangles, quadrilaterals etc. in a complex figure.

To count the number of lines, add all the horizontal, vertical and slanting lines.

To count the number of triangles, add all the number of triangles composed of 1 component, 2 components, 3 components and so on.

The same process is for counting the number of other polygons.





 Count the number of squares in the given figure.

(a) 7                              (b) 6                              (c) 9                              (d) 10


Explanation (a):

The squares composed of two components each are ABCK, CDEL, JKHI, HLFG and KCLH, i.e. 5 in number.

The squares composed of four components each are ACHJ and CEFH, i.e. 2 in number.

 Total number of squares in the figure =5+2=7.
