Given: If a triangle is isosceles, then it has two congruent sides. If a triangle has two congruent sides, then it has two congruent angles. A KLM is isosceles. Select the valid conclusion(s) from the given statements. Select all that apply. A) Law of Detachment; A KLM has two congruent sides. B) Law of Detachment and Law of Syllogism; A KLM has two congruent angles. C) Law of Syllogism; If a triangle two congruent angles, then it has two con- gruent sides. D) Law of Syllogism; If a triangle is isosceles, then it has two congruent angles. E) Law of Syllogism; If a triangle has two congruent angles, then it is isosceles. F) No valid conclusions; because the third statement does not satisfy the hy- pothesis of the second statement, a valid conclusion cannot be made.
