Answer:
GB
Explanation:
Given:
BC = BD
DE is ⊥ to AC.
GB is ⊥ CD.
we need to find the perpendicular bisector from the given figure.
Solution:
By Definition of Perpendicular bisector which states that;
" If a line which is perpendicular to the segment such that it bisects the segment in 2 equal parts then it is said to be perpendicular bisector."
From the above figure we can see that;
Line GB is is ⊥ segment CD.
Also BC = BD (given)
Hence Line GB is a Perpendicular bisector.
