In ∆ABC, AB = 5 c

Answer :

Given: AB = 5 cm

BC = 8 cm


CA = 7 cm


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.



By the midpoint theorem,


DE = �AC


DE = � × 7 cm


DE = 3.5 cm


Hence, the length of DE = 3.5 cm
