nvm, i found out how to do it
i still cant seem to get Q3 part b.
I created tons of inequalities and put them in terms of other lines.
Then I added some of the inequalities together and I couldn't get the rest

would we need to use median ratios?
In triangle ABC, the medians AD,BE, and CF concur at the centroid G.
(a) Prove that AD < (AB + AC)/2.
(b) Let P=AB+AC+BC be the perimeter of triangle ABC. Prove that 3P/4 < AD + BE + CF < P.
Please help asap! Include solution too. Thank you!
