5-2 Medians and Altitudes of
Triangles
MS. ANDREJKO
Real World
Vocabulary
Median- a segment with endpoints being a vertex of
a triangle and the midpoint of the opposite side
Centroid- the point of concurrency of the medians
of a triangle
Altitude- a segment from a vertex to the line
containing the opposite side and perpendicular to
the line containing that side
Orthocenter- The lines containing the altitudes of
a triangle are concurrent, intersecting a point called
the orthocenter
Theorems
5.6- The angle bisectors of a triangle intersect at a
point called the incenter that is equidistant from
each side of the triangle.
5.7- The medians of a triangle intersect at a point
called the centroid that is two thirds of the distance
from each vertex to the midpoint of the opposite
side.
