    ok so let's see if you get this. if you can find the total sum of all the angles and divide it by the number of angles, you can get the value of one of the angles... makes sense?

    there's a formula for it. Sum = (n-2)*180 where n is the number of sides of the polygon, in this case 8.. so let's do the first part. find the sum of the angles and tell me what you got :)

    I see what I done wrong. thanks for showing me. I have one more problem if you can show me how to do it. It has to do finding coordinates.
