Figure 3.25. Exercise 3.2.10: Dart ABCD where AB = BC and AD = CD 10. A dart is a nonconvex quadrilateral with two pairs of congruent adjacent sides. The nonconvex quadrilateral ABCD shown in Figure 3.25 is a dart since AB = BC and AD = CD. Prove that the lines containing the diagonals of a dart intersect at right angles.
