Answer:
= 9
Step-by-step explanation:
The given parameters are;
The point of intersection of the perpendicular bisectors of the sides ,
, and
intersect (meet) at point G
Let D represent the point of intersection of the perpendicular bisector from G to , we have for ΔBGD and ΔCGD;
≅
by reflexive property
∠GDB = ∠GDC = 90° given that is the perpendicular bisector of
Similarly, ≅
, also given that
is the perpendicular bisector of
Therefore;
ΔBGD ≅ ΔCGD by Side-Angle-Side (SAS) rule of congruency
≅
by Congruent Parts of Congruent Triangles are Congruent, (CPCTC)
=
= 9 by definition of congruency
∴ = 9.
