please prove 4G. Suppose a, , , andd are four distinct rays with the same endpoint, such that a and d are opposite rays and a *b*. Show that Lab, Lbc, and Lcd form a linear triple. (In other words,...
4G. Suppose a, , , andd are four distinct rays with the same endpoint, such that a and d are opposite rays and a *b*. Show that Lab, Lbc, and Lcd form a linear triple. (In other words, condition (iii) in the definition of a linear triple is redundant.) (Hint: Use the interior lemma.]
