Question

how many square rectangle and triangle are there in the fig ?​

Answer 1

Answer:

Number of triangles in Fig – 1 = 8

Hint: Here having total two diagonals and having four blocks. So formula for that 4 x 2 = 8 number of triangles.

Figure – 2 : Number of triangles in Fig – 2 = 16

Hint: Here having total two diagonals and having eight blocks. So formula for that 8 x 2 = 16 number of triangles.

Figure – 3 : Number of triangles in Fig – 3 = 18

Hint: Here each square having 8 no. of triangles and combine squares having 2 no. of triangles. So total number of triangles – 8 + 8 + 2 = 18.

Figure – 4 : Number of triangles in Fig – 3 = 28

Hint: Here each square having 8 no. of triangles and combine squares having 4 no. of triangles. So total number of triangles – 8 + 8 + 8 + 4 = 28.
