The given statement is a valid
geometric proposition.
Statement: If a triangle has two
congruent angles, then it is an
isosceles triangle.
a) Write the contrapositive of
this statement:
b) NOW, Determine if the
contrapositive statement is
valid. Explain your reasoning.
a) If a triangle is not
isosceles, then the
triangle does not have two
angles that are congruent.
b) The contrapositive
statement is valid. The
triangle could be equilateral,
which is also isosceles. It
could also be scalene, with no
congruent angles. Also, the
contrapositive of a true
statement is always true. If a
statement is false, its
contrapositive will be false
also.
