THE AREA METHOD AT THE PRIMARY LEVEL WITH MEDIAN LINE PROBLEMS
Keywords:Triangle, Area, Ratio, Altitude, Base side
When solving any problem or geometry problem, we often have thoughts and find the other solutions or how to discover new problems from the original problem. For geometry problems, in order to have a new problem we often change or add sumptions/conclusions
and etc. In this work, it comes from solving
the median line problem in primary level. We will develop and
expand it to include new problems on the basis of changing the
ratio of each dividing point on the two sides of the triangle and/or
adding appropriate assumptions.
