Question

if a points (-1,3),(1,-1)&(5,1) are the vertices of a triangle then find the length of a median drawn from (-1,3) ?

Answer 1

Answer:

5 units

Step-by-step explanation:

mid point of (1,-1) and (5,1) = (1+5)/2 , (-1+1)/2 = (3,0)

median from (-1,3) will join the other line on (3,0)

so the length of median will be length of line segment from (-1,3) to (3,0)

i.e. √{ (0-3)^2 + (3- -1)^2}

= √(3^2 + 4^2)

=√25

= 5 units

Answer 2

Answer:

Use Mid point Formula

& Distance Formula

Step-by-step explanation:

$x1 + x2 \div 2 = x \\ y1 + y2 \div 2 = y\: \\ mid - point \: formula$

$\sqrt{(x2 - x1) {}^{2} } + (y2 - y1) {}^{2} \\ distance \: formula$
