figure jklm is a rectangle, so manglekjm = mangleklm = 90° and anglekjc is-congruent-toanglemlc. a rectangle has corner points j, k, l, m going clockwise. 2 lines are inscribed within the rectangle. one line goes from k to m, and the other line goes from j to l. both lines intersect in the middle to form point c. all lines in the rectangle are the same length. which reason justifies the statement that angleklc is complementary to anglekjc?
