Can you identify these arch-way pieces I'm considering starting a project inspired by some of the Arab-style buildings I've seen. Most of them use a sort of curved archway around the windows. I can't figure out how to duplicate it. Can anyone identify the pieces used here to form the curved archways?

Any other suggestions for making a cool arab scene (for a relatively new builder)
You are, most likely, interested in identifying following arch:

The other arch as seen in second picture is the following one:
