PROPERTIES OF CIRCLES

c::J Guided Invesligalion 7.8~ PARALLEL LINES THROUGH A CIRCLEStep 1:Take one of your patry papers with a circledrawn on it. Use your straightedge to draw apair of parallel lines passing through the circle.Step 2:Compare the sizes of the arcs between theparallel lines by folding one arc onto the other.How do the lengths of the arcs compare? Are thetwo arcs outside the parallel lines the same size?, ,Step 3:Repeat steps 1 and 2 with another pair of parallel lines. (If possible, use a different-widthruler to draw your lines.)Compare your results with the results of others near you. Your next patry paper conjecture could be:~ 51 Parallel lines intercept _________________ arcs on a circle.PROPERnES OF CIRCLES I I 3
