Question

EXERCISE 6.1
1. In quadrilateral ACBD,
AC = AD and AB bisects ZA (see Fig. 6.16). Show
that A ABC = A ABD. What can you say about
BC and BD?​

Answer 1

Answer:

(Given) :In quadrilateral ACBD

AC=AD

AB bisects ZA

(Show that ) : ABC = ABD

BC and BD

BC = AD

AC = DB ( It is a rectangle)

BDA = BCD ( by Rhs congruency rule)

AB bisect ZA

CB = CB ( common)

Z is a mid point

BC = BD ( hence proved)
