If the length ratio of the two diagonals of the diamond is 1:3, the degree of the smaller inner angle of the diamond is 0______ Degree

If the length ratio of the two diagonals of the diamond is 1:3, the degree of the smaller inner angle of the diamond is 0______ Degree

Because the diagonals of the diamond are perpendicular to each other and equally divided into a group of diagonals, the tangent value of half of the smaller inner angle of the diamond is 1:3, then half of the smaller inner angle of the diamond is 30 ° and the degree of the smaller inner angle of the diamond is 60 °
