4 and 5 point perspective Carole

I had great difficulty putting the lines on the circle and never did get them accurate.  I couldnt get the ellipses accurate and the right distance apart.  I do understand the concept.  I did a lot of measuring. free handed them as best I could. There is something missing in my understanding how to execute this.  I see Yusra was able to get them on paper correctly, how is she doing it?
