In geometry it is a line that crosses two non-consecutive angles in a figure of at least 4 sides, or in a body of at least 4 faces. In town planning is a straight road that joins two points of the city cutting the apples without respecting its classic square plant, and its distribution in "checkerboard". Latin Diagonalis took it from the Greek 948; 953; 945; (Dia "through") 947; 969; 957; 953; 945; (Gonia "angle").
