আমি ছবিতে 276 টা ত্রিভুজ পেয়েছি। কেউ একটু দেখবেন যে আমার গণনায় কোনো ভুল আছে কিনা?

It’s 276 in my case also.

Triangles with 1 small triangle are 80

Triangles with 2 small triangle are 72

Triangles with 4 small triangle are 32

Triangles with 8 small triangle are 44

Triangles with 16 small triangle are 20

Triangles with 18 small triangle are 20

Triangles with 30 small triangle are 4

Triangles with 38 small triangle are 4

So, total triangles are 80+72+32+44+20+20+4+4=276

Thanks for removing the confusion. I solve the problem in the same way.
