okay I will try to change ur mind
take a look at this illustration, in each of the highlighted triangles you have smaller triangles:
1 -> is a triangle
1, 2 -> make a triangle
1, 2, 3 > make a triangle
and so on, you can clearly see tons of triangles already

But honestly, I just wanted you to get the link of the original image which will lead u to: mathsisfun.com
then if you just google my question and add the site mathsisfun.com
you will get the solution, which is:
64 Triangles
36 Quadrilaterals
Total: 100 shapes.
