A) \[\Delta ABC\] and \[\Delta \,CBD\] are isosceles triangles.
B) BD bisects \[\angle ADC\]
C) BD bisects \[\angle BAD\]
D) \[\Delta ABC\] and \[\Delta CBD\] are equilateral triangles.
Correct Answer: B
Solution :
Since \[\Delta ABD\] and \[\Delta CBD\] are congruent, \[\angle ADB=\angle CDB\] (Corresponding parts of congruent triangles). \[\Rightarrow \] BD bisects \[\angle ADC\]You need to login to perform this action.
