points D(2,-3), E (-1,7) and F(3,5) are midpoints of the sides BC, CA and AB of a triangle. what re the equation of its sides??
does anyone know how to do this question??
Draw a small sketch. You can notice that lines connecting two points points D, E and F (in whatever pair) are parallel to the sides of the triangle, therefore equal gradients. Find those gradients, and then use y−y1=m(x−x1) with points D, E and F where appropriate.

so would i use y2 - y1/ x2-x1 for each of the coordinate pairs to find gradient?
