I’ve also seen regular bold and hashed bonds without wedge shapes used for both purposes. So there is some variability; I guess it depends on who you learned your chemistry from.

But that is perhaps better covered in stereochemistry and is probably covered elsewhere on the site.

Thanks – I edited it to include “syn addition”. However the product is cis-dimethyl cyclohexane so I thought it would be best to write it as the “cis” product.
