Question

, AB=AC and D is any point on BC produced. show that AD>AB

Answer 1

Step-by-step explanation:

AB = AC

angle abc=angle acb(angles opposite to equal sides of a triangles are equal)

angle ABC is exterior angle for triangle abd

angle abc> angle adb

angle acb>angle adb

=>angle acd >angle adc

ad>ac (side opposite to larger angle in triangle adc

ad>ab(ab=ac, given)

hence proved
