If lr = 12 and pr = 4, find lp. explain. lp = 16 because lr + pr = lp according to the segment addition postulate, and 12 + 4 = 16 using substitution. lp = 8 because lp + pr = lr according to the segment addition postulate, and 8 + 4 = 12 using substitution. lp = 16 because 12 + 4 = 16 according to the addition property of equality. lp = 8 because 12 − 4 = 8 according to the subtraction property of equality.
