A B K J P Q L D C M The figure t the left cnnot be trced, but the one t the right cn. The rule is tht figure is trceble if it hs no more thn two points where n odd number of segments meet. The figure t the left hs three segments meeting t ech of the four corners. However, the figure t the right hs only two points, L nd Q, where n odd number of segments meet. Determine if ech figure cn be trced without trcing the sme segment twice. If it cn, then nme the strting point nd nme the segments in the order they should be trced. 1. E F.
