To start, find the equation s of the lines AB, BC, CA and their midpoints.

Exactly where are you stuck?

Have you at least drawn a diagram?

 

[Sam Sun]

I have drawn the diagram. I've done Number 1 with no problem.
But I'm having problems with all the other parts of the question (ii,iii,iv)

 

[pka]

You have done part i). Did you find that the midpts are the averages of the endpts?
For II) the median from point \(A\) is the line segment \(\overline{AD}\), where \(D\) is the midpt of \(\overline{BC}\).

find the equation s of the lines AB, BC, CA and their midpoints.

Where is the midpoint of BC (co-ordinates) - let's call it D?

Where is the co-ordinate of vertex A ?

What is the equation of AD?

Hint: equation of a line joining (x1, y1) and (x2, y2) is:

\(\displaystyle \frac{y - y1}{y2 - y1} \ = \ \frac{x - x1}{x2 - x1}\)
