In
, AD is the perpendicular bisector of BC (see figure). Show that
is an isosceles triangle in which AB=AC.
Solution:
In
and
, we have
AD=AD (Common)
(Each given equal to
)
(Given)
Therefore, by SAS rule,
.
Hence, AB=AC (Corresponding parts of congruent triangles are equal)
AB=AC means that
is isosceles.
