Question 1031049: Suppose AB=AD in trapezoid ABCD with base segment BC. Make a sketch and prove that segment BD bisects angle ABC Answer by mananth(16946) (Show Source):
AD || BC OPP SIDES OF TRAPEZIUM
ANGLE ADB = ANGLE DBC (ALTERNATE ANGLES)
In triangle ABD AB = AD ( given)
angle ABD = angle ADB (isosceles triangle theorem
Therefore ABD = DBC
Therefore BD bisects angle ABC
