If you know the end points then use the distance formula or simply use a ruler.
A ruler or tape measure can be very useful.
The distance between two points on a line is the absolute value of the difference between their coordinates. This can be calculated using the distance formula: |x2 - x1|, where x1 and x2 are the coordinates of the two points.
The printed ruler on map is called the scale. It shows distance per inch. You can take a strip of paper, lay it alongside the ruler, mark the paper--- then, take the marked paper to measure distance between two points on the map.
Ruler PostulateThe ruler postulate states that: Every point on a line can be paired with a real number.The number associated with a point A on the line is called the coordinate of A.Two arbitrary points can be paired with the numbers 0 and 1, defining the length of a unit.The distance between any two points A and B is designated AB.The distance between two points A and B can be found by taking the absolute value of the difference of their coordinates: AB = |A - B|. Note that this implies that a distance is always positive.

You should use a special device for measuring angles - a protractor. With a ruler, it is much more complicated, but still possible: you can mark two points on the angle, one on each side; measure the distance from the vertext of the angle to those points; measure the distance between the points; then use the Law of Cosines to calculate the angle.
You look at the SCALE of the map. This usually has a line marked with mileage. You measure a sample of that mileage with a ruler , then compare it to the distance between the 2 points. - For instance, if 100 miles is equal to an inch, and the 2 points are 4 inches apart, then the distance is 100 x 4 , or 400 miles.
A map scale lets you convert map distance to ground distance.
