Q: primary parts of a triangle

A: Answer:
Basic and secondary parts of a triangle?
Answer:
A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments. [ A triangle with vertices A, B, and C is denoted ABC.
In Euclidean geometry any three non-collinear points determine a unique triangle and a unique plane (i.e. a two-dimensional Euclidean

space).
the secondary parts of the triangle
median - a segment whose endpoints are a vertex of the triangle and the midpoint of the opposite side
angle bisector - a segment which bisects an angle and whose endpoints are a vertex of the triangle and a point on the opposite side
altitude - a segment from the vertex of the triangle perpendicular to the line containing the opposite side
perpendicular bisector - a line whose points are equidistant from the endpoints of the given side
incenter - the point of concurrency of the three angle bisectors of the triangle
centroid - the point of concurrency of the three medians of the triangle
orthocenter - the point of concurrency of the three altitudes of the triangle
circumcenter - the point of concurrency of the three perpendicular bisectors of the sides of the triangle
