    The sum of the inner angles of the regular n-sided is: (n-2)*180, so there is:

    Sum of regular 3-sided inner angles = (3-2) * 180 = 180 each inner angle = 180 3 = 60 degrees.

    Sum of regular 4-sided inner angles = (4-2) * 180 = 360 Each inner angle = 360 4 = 90 degrees.

    Sum of the internal angles of a regular 5-sided = (5-2) * 180 = 540 each inner angle = 540 5 = 108

    Degree. Sum of regular 6-sided inner angles = (6-2) * 180 = 720 each inner angle = 720 6 = 120 degrees.

    Sum of regular 7-sided inner angles = (7-2) * 180 = 900 each inner angle = 900 7 = degrees.

    The sum of the internal angles of a regular n-sided shape is equal to the difference of n minus 2 multiplied by 180, as the difference between the triangle n is 3 internal angles and 3 minus 2 multiplied by each internal angle and divided by n, and 180 divided by 3 is 60 degrees. a divided by n

    A regular dodecagonal can be divided into 12 equilateral triangles. Since the sum of the internal angles of the dodecagonal wheel is 180°*(n-2), where n represents the number of sides, the sum of the inner angles of the regular dodecagonal is 180°*(12-2) =180°*10 = 1800°.
