Count the number of triangles and squares in the given figure.

36 triangles, 7 squares
38 triangles, 9 squares
40 triangles, 7 squares
42 triangles, 9 squares
Answer: Option
Explanation:

The figure may be labelled as shown.

Triangles:

The simplest triangles are BGM, GHM, HAM, ABM, GIN, UN, JHN, HGN, IKO, KLO, LJO, JIO, KDP, DEP, ELP, LKP, BCD and AFE i.e. 18 in number.

The triangles composed of two components each are ABG, BGH, GHA, HAB, HGI, GIJ, IJH, JHG, JIK, IKL, KLJ, LJI, LKD, KDE, DEL and ELK i.e. 16 in number.

The triangles composed of four components each are BHI, GJK, ILD, AGJ, HIL and JKE i.e. 6 in number.

Total number of triangles in the figure = 18 +16 + 6 = 40.

Squares :

The squares composed of two components each are MGNH, NIOJ and OKPL i.e. 3 in number.

The squares composed of four components each are BGHA, GIJH, IKLJ and KDEL i.e. 4 in number.

Total number of squares in the figure = 3 + 4 = 7.

How many maximum lines are there? Anyone, explain it.

In a square, there are totally 8 triangles and there are totally 4 squares and count num of points in which squares are joined that is 6+two triangles.

4*8=32+6+2=40.

In case of squares, there are 4 squares over here+num of points in which squares are joined /2=total num of squares.

So; 4 + 6/2 = 7.

AGJ is counted "The triangles composed of four components".

Mohamed said:   8 years ago
Why you didn't count AGJ?

What do you mean by two component?
