    an apothem is a line drawn from the center of the shape to the outside. Like a radius of a circle.

    the thing is; is this radius of a circle drawn insid the shape of outside the shape? inside would mean the apothem = radius

    360/8 = 45 degrees as a central angle and each 'other' angle of the is (180-45)/2

    Well, we're assuming that the octagon has all angles equalling 360 degrees.

    your apothem = r sin[(180-45/2)]

    an isoceles triangle with a top angle of 45 has 67.5 as its two bottom angles
