Why does science tree in grade three have gum? Why is gum sticky
Gum is a kind of protective substance secreted by trees after injury. It can promote wound healing and secrete toxins or other irritating substances and tastes to drive away invaders!
The overall shape of a tree consists of crown, () and ()
Trunk, root
As shown in the figure, let m be the center of gravity of △ ABC, and am = 3, BM = 4, CM = 5, then the area of △ ABC is______ ．
Extend BM to AC at point D, and then extend BD to e, so that de = DM, connect CE, ∵ m is the center of gravity of △ ABC, ∵ ad = CD, MD = 12bm, ∵ ADM = ≌ CDE (equal to vertex angle), de = DM, ≌ AMD ≌ CDE (SAS), ≌ am = EC = 3,
