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?
S
T
O A. Draw TV so that Vis the midpoint of SU, then prove ASTV = AUTV
using SSS.
B. Draw TV bisecting T, with Von SU, then prove ASTV = AUTV
using AAS.
OC. Draw TV so that Vis the midpoint of SU, then prove ASTV = AUTV
using SAS.
OD. Draw TV bisecting T, with Von SU, then prove ASTV = AUTV
using ASA.
