Question

If the points A(1,-1) B(-1,3) and C(5,1) are the vertices of triangle ABC find the length of the median through B​

Answer 1

midpoint of AC =

$(1 + 5) \div 2$

$( - 1 + 1) \div 2$

(3,0) mid point of AC

median through B will pass through mid point of AC (3,0)and point B(-1,3)

By distance formula,

$\sqrt{(3 - 0) {}^{2} + ( - 1 - 3) {}^{2} }$

=√9+16

=√25

= 5 units
