Can some please help me with this question, I know how to find them when given the full length but how do you find the length when given half the length??

phi · Answer

Use this fact:
The centroid is exactly two-thirds the way along each median. 
Put another way, the centroid divides each median into two segments whose lengths are in the ratio 2:1, with the longest one nearest the vertex.

can you answer any of the questions ?

Yeah I can answer the ones when given the full length like the first on I got I just multiplied 18 by 2/3 and i got it right

thanks phi ill give you a medal but i solved it hahah thanks though

phi · Answer

does that you mean you figured out:
1) if they give you the "long part"  (from the centroid to the vertex), then the "short side" (from the centroid to the side)  is ½ as long

2)  if they give you the short side, the long side is twice as big as the short side ?
