Question

If a triangle has two congruent sides, the triangle is isosceles.
State the contrapositive of the conditional statement.
A)
If a triangle is isosceles, then the triangle has two congruent sides.
B)
If a triangle has two congruent sides, then the triangle is not isosceles.
C)
If a triangle is not isosceles, then the triangle does not have two congruent sides.
D)
If a triangle does not have two congruent sides, then the triangle is not isosceles.

Answer 1

Contrapositive: if ~q, then ~p.
So, If the triangle is NOT isosceles, then it does NOT have 2 congruent sides.
