1.(ii) ∆ ABC and ∆ DBC are two isosceles triangles on the same base BC and vertices A and D are on the same side of BC (see Fig). If AD is extended to intersect BC at P, show that
Consider and ,
(i) is common side in both the triangles.
(ii) (This is obtained from the c.p.c.t. as proved in the previous part.)
(iii) (Isosceles triangles)
Thus by SAS axiom, we can conclude that :
