The isosceles triangle theorem says "If two sides of a triangle are congruent,
then the angles opposite those sides are congruent. "
If you are using this figure to prove the isosceles triangle theorem, which of
the following would be the best strategy?
K к
O A. Draw KM bisecting ZK, with Mon JL, then prove AJKM ALKM
using ASA
B. Draw KM so that Mis the midpoint of JL, then prove AJKM * A
LKM using SSS
C. Draw KM bisecting K with Mon JL, then prove AJKM * ALKM
using AAS
D. Draw KM so that Mis the midpoint of JL, then prove AJKM * A
LKM using SAS.
