In every type of triangle, the median will be contained within the polygon, unlike altitudes which can lie outside the triangle.
The point of concurrency of the medians is called the centroid.
The altitude is the line perpendicular to the selected base from the opposite vertex.Patruno's proof Broken Chord Theorem:.Math Worksheets, high School Math based on the topics required for the Regents Exam conducted by nysed.You can choose any side to be the base.Long Multiplication, less, Equal, More, listing All the Composite Numbers, lucky Numbers.14 :p.282,p.358 If the altitude from the hypotenuse is denoted h c, then h c 2 4 ( a b ) displaystyle h_cleq frac sqrt 24(ab) with equality only in the isosceles case.
