Counting triangles

Hi.. we heard...
"Mathematics is the queen of science"

Yes... It has a bonding with the heart in all departments.

We can see maths everywhere if we deeply search about...
A very big project that might start with a calculation...

We can even have fun with the Queen 😉

Wondering!!??

Let's have a riddle... find the number of triangles
Can you count how many triangles are there?

Come we have tips

Tip: Counting triangles with in Square, Rectangle, Quadrilateral 

Find the number of triangles in the above figures

Figure – 1 : Number of triangles in Fig – 1 =  8

Hint: Here we have totally two diagonals and having four blocks. So the formula is no.ofblocks ×diagonals (4 x 2 =8number of triangles).

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

Hint: Here we have  two diagonals and 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.
