Turkey spans nearly 18.5 degrees of longitude, between about 26°24' east at Canakkale to 44°46' east at the point where Turkey, Iran, and Iraq meet. On your map, you're welcome to subdivide that span into as many or as few intervals as you're comfortable with, and to draw the lines to indicate the various meridians. Keep in mind that a greater number of lines permits more precise estimates of longitude, but they do tend to cover up stuff on the map. But the choice is entirely up to the owner of the map.

Thus, the half of the map east of 100 degrees west is in the Western Hemisphere.
