In the figure below, points ( D, E ), and ( F ) are the midpoints of the sides of ( riangle A B C ). Suppose ( D F=34, A C=48 ), and ( B C=78 ). Find the following lengths. ( D E= ) ( A B= ) ( B E= )

Step 1
So, since D and F are midpoints of sides AB and AC, respectively, we have: DF || BC and DF = (1/2)BC Now, we are given that DF = 34 and BC = 78. So, we can write: 34 = (1/2)(78) Now, let's find DE. Since D and E are midpoints of sides AB and AC, respectively, Show more…
