AE = EC and BF = FC. EF = 8 and DF = 10. AB = [?]

Answer:
Therefore AB is 16 units.
Step-by-step explanation:
Given:
AE = EC
BF = FC
EF = 8 and DF = 10
To Find:
AB = ?
Solution:
Mid Point Theorem:
The Midpoint Theorem states that "the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side".
AE = EC .....Given
Therefore E is the Mid Point of AC.
BF = FC .....Given
Therefore F is the Mid Point of BC.
Therefore,
EF || AB ........................Mid Point Theorem.
[tex]EF=\dfrac{1}{2}AB[/tex] ..............Mid Point Theorem.
Substituting the values we get
[tex]8=\dfrac{1}{2}AB\\\\AB=8\times 2=16\ units[/tex]
Therefore AB is 16 units.
