- 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.
