if you mean which countries have borders that are entirely made up of straight lines like say the state of Utah then none but if you mean which countries have borders that include at least some lines that are entirely or perfectly straight then probably all or nearly all A few examples like Papua New Guinea and Egypt do however come close to entirely straight borders Land borders are defined by border markers. These are placed by mutual agreement by the two countries and mark out the border. They can be anything from a few tens of metres apart to a few Km apart. Normally they are within sight of each other. The border is deemed to run in a straight line from on border marker to another. Most borders are therefore a large number of relatively short straight lines, and most borders are defined by straight lines. This does not apply to borders which run along rivers or lakes. in this case the border is normally the centre of the river, which is not a straight line. Note a line of latitude (xx °N or yy °S) is not a straight line.
Brazil borders 10 countries and Russia borders 13 countries.
Four states in the United States have straight line borders: Colorado, Wyoming, Utah, and New Mexico. These straight line borders were established through surveying techniques rather than natural geographical features.
