Any triangle can be dissected into three mirror-symmetric pieces. If we are limited to just two pieces, is the number of (non-congruent) triangles that admit a dissection (into mirror-symmetric pieces) finite or infinite? Veit On Feb 13, 2012, at 5:42 PM, Veit Elser wrote:

Okay, I'll try again:

Which triangles can be dissected into two pieces, both of which are mirror-symmetric?

Veit -- Can the word "just" be omitted without changing the meaning here, or is it in some way limiting the number of mirror-symmetric pieces that such a triangle can be dissected into?

Thanks,
