Method.1Method.1 　　Made a miniature copy as a model of orthogonal road Made a miniature copy as a model of orthogonal road city or radially circle road city like this photograph.city or radially circle road city like this photograph.

Orthogonal road city Radially circle road city

Method2.Method2.Throw two coins. Throw two coins.

Then, measure the distance and distance along road Then, measure the distance and distance along road between the points which two coins fell.between the points which two coins fell.

Measure the distance with a ruler.
