Midsegment Theorem

What facts do we know about a midsegment of a triangle? The 3rd side is twice as long as the midsegment The midsegment is 1/2 as long as the third side The midsegment is parallel to the third side All of the above What is the length of segment EC if DE is the midsegment? A D EC = B 6 E C What is the length of segment DE? A D DE= B 24 E DE is the mid- segment of the triangle. C BD is the midsegment of triangle ACE. Find the value of x. A B 16 x C E D x = G A H C B Use ∆GHJ, where A, B, and C are midpoints of the sides. J AB = If AB = 3x+8 and GJ = 2x+24, what is AB? G A H C B Use ∆GHJ, where A, B, and C are midpoints of the sides. J If AC = 3y-5 and HJ=4y+2, what is HB? HB = G A H C B Use ∆GHJ, where A, B, and C are midpoints of the sides. J If GH = 7z-1 and BC = 4z-3, what is GH? GH = A LN CB is parallel to L Segment AB ?
