The centroid of a triangle is the intersection of the three medians of the triangle (each median connecting a vertex with the midpoint of the opposite side).
The least amount is 2 packs. i know this becaus first i make a lcm chart which looks like this : 8: 8,16,24,32 12: 12,24 i then see that the lcm is 24 and 12+12 is 24 meaning that i will have to buy 2 packs of large plates.
