Question

please help me to answer this..
find the coordinates of the intersection of medians of the triangle whose vertices are (1,3), (-2,4) and (1,-2).
thanks!!

Answer 1

you essentially need to develop 2 lines that intersect. use the perp slope from one set of points and anchor it to the remaining point.

Answer 2

if the slope between 2 points is: a/b, then the perp slope is -b/a

when given a slope, m, and a point(xo, yo), a line equation can be constructed in point slope format as:

y - yo = m(x-xo)
