Question

Solve the following problems:

Chapter Reference

c

Given: △ABC, D ∈ ray 

BC

 

     C∈

BD

, AB=AC=BC

    Prove: BD>DA>AB

Answer 1

Each angle A,B,C= 60°; angle ACD=120°. If angle BAC and angle CAD are complimentary; angle CAD=30°; and angle ADC=30°. If this drawing is up-to-scale; whatever I said about ACD is false. So BD>DA>AB.
