How many triangles does the inscribed pentagram in a pentagon contain?

It's 35. I just counted it. I'll draw a picture later.

Hmm (expressing hesitation, etc.) ... I'm really embarrassed to take it out, hehe.

What a nice painting. ....

It is difficult to control with the mouse. I've been painting for a long time. I hope you can understand. My painting is a bit messy ... but it should be more intuitive.

This is a new painting this afternoon. Although it's still ugly, it's much better than the one in the morning. Hehe, I'll just make do with it. My PS is not very good, and it has been like this for a long time.

It consists of a triangle that has not been redrawn. Look at the following, starting with two:

This is a triangle with 10 * *.

This is made up of two small triangles.
