Colorado and Wyoming are the two US states with borders made up of 4 straight lines.
1. Colorado 2. Utah 3. New Mexico 4.Wyoming EDIT: Actually there are only three since the New Mexico/Texas border near El Paso is not straight.
It made the Sabine river the eastern border It also made the top
Some borders are made by natural features, such as rivers. Other times, there might be a straight line determined by geographical latitude or longitude.
Because of state borders. Why is California so big? Because people made state borders and Rhode Island is small because of it.
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.
Its hard because of the population that is their. Also it was hard because a large area of it was wealthy. This made it hard to colonize Texas.
because the Moses and Steve Austin made Texas
