    Hey rcs.

    I'm in agreement with you: I have no idea what this actually means.

    I would offer a speculation that it turns a triangle into a quadrilateral on the x-y plane.

    Re: Find the measure of angle BCD

    The question is not clear. Pl check which side is being produces. I feel it might be AC. In that case you will have angle ACB = ( 180 - angle A - angle B)= 180 - 60-85= 35
    So angle BCD = 145 ( Linear pair )
