If an argument reads
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 ?3s/2 units.
If the height of an equilateral triangle is ?3s/2 units, then its area is ?3s2/4 units2.
Then we can deduce
(a) If ?ABC is an equilateral triangle with perimeter 3s units then its area is ?3s2/4 units2.
(b) If the area of ?A|BC is| ?3s2/4 units2 then it is an equilateral triangle
(c) If each edge of an equilateral triangle is s units long then its area is ?3s2/4 units2.
(d) All of these are valid conclusions.
(e) Both (a) and (c) are correct.
(e) Both (a) and (c) are correct.
