Show that the midpoint of the line segment joining the points (a,b) and (c,d) is

May be I'm just thinking too much, do I just simply use the midpoint formula here? Or do I have to do something more?

1)Take for example (0,1) and (1,0) to illustrate.

2)Plot these point

3)Draw a line segment from (0,1) down and draw a line segment from (1,0) left.

4)Those intersect as (0,0)

5)By similar triangles if (x,y) is midpoint then x is midpoint of vertical line segment and y is midpoint of horizontal line segment. - Jan 18th 2008, 03:41 AMmr fantastic
