How to find the centre of a circle using a piece of paper

video How to find the centre of a circle using a piece of paper
0:11 I drew a circle using a compass so we could see the centre of the circle by the mark left from the point.
0:36 Now using a piece of A4 paper, with square 90 degree edges, place the corner on the edge of the circle and mark where the two sides intersect. 
0:50 Draw a line.
1:00 Repeat this anywhere within the circle and draw another line.
1:23 Where these two lines intersect you will find the centre, which in this case is practically on the compass point.
