If an argument reads

Question

If ?ABC is an equilateral triangle with perimeter 3s units then each edge of ABC is s units long.

If each edge of an equilateral triangle is s units long then its height is

units

If the height of an equilateral triangle is



units, then its area is





Then we can deduce



(a) If ABC is an equilateral triangle with perimeter 3s units then its area is



(b) If the area of ABC is



then it is an equilateral triangle

(c) If each edge of an equilateral triangle is s units long then its area is



(d) All of these are valid conclusions.

(e) Both (a) and (c) are correct.

Answer 1
