# Find the lengths of the medians AD and BE of ΔABC whose vertices are A(7, -3), B(5, 3) and C(3, -1).

Answer :

A **median of a triangle** is a line segment joining a vertex to the midpoint of the opposing side, bisecting it.

fig.4

Mid-point of side BC opposite to vertex A i.e. coordinates of point D is given by-

= (4,1)

Mid-point of side AC opposite to vertex B i.e. coordinates of point E is given by-

= (5,-2)

Length of Median AD is given by-

= √(9 + 16)

= √25

= 5 units

Length of Median BE is given by-

= √(0 + 5^{2} )

= √25

= 5 units

Thus, Length of Medians AD and BE are same which is equal to 5 units.
