Again my aim with these posts is to explore the problem solving process and how one can experiment towards the proper approach.

It's a good example of trying different ideas to utilize angle bisectors. Plus, if you haven't checked out this site, its well worth the time.

But traditional approaches like this don't tell us why we should be interested in finding the center of a triangle in the first place.

Then construct the three medians of a triangle, the segment from the vertex to the midpoint of the opposite side. Where the three medians are concurrent is ...

To start, two triangles with the same altitude have different bases, ratio of their areas is just the ratio of their bases.

Q.Consider a triangle ABC whose sides AB,BC,AC are represented by the straight lines 2x+3y=0, x+py=q, x-y=3 respectively The point P is (2,3) then solve ...
