AB is a line segment and P is its mid-point. D and E are points on the same side of AB such that and . (see Figure). Show that
(P is the mid-pont of AB) (2)
Therefore, from (1), (2) and (3), we can say that by ASA rule,
From solution (i), we know that by ASA rule, .
Therefore, (Corresponding parts of congruent triangles are equal)
