    For people who like a formula:
    INTERIOR: (n - 2) x 180
    EXTERIOR: 360 / n
    n = number of sides

      Very useful tips, but for the interior angles it would give you the sum of all interior angles together, so it must be further divided by the number of sides ( which is ofc the same as the number of angles).
      In order to get the measure of just one angle.🙂

    • @TheGCSEMathsTutor

      NIMA M If you watch from 0:40 this should hopefully explain it better than I can in the comments 😁 essentially if you pick one of the vertices it can then be split into triangles but as it is already connect to 2 other vertices it will only be able to make 2 less triangles than the amount of sides!
