Term
 altitude
Definition
 An altitude is also a line which passes through a vertex of a triangle, and is at right angles to the opposite side. A triangle has three altitudes.http://www.mathopenref.com/altitude.html
Term
 Orthocenter
Definition
 the intersection on the altitudes of a triangle
Term
 perpendicular bisector
Definition
 A line or line segment that passes through the midpoint of a side of a triangle and is perpendicular to that side.
Term
 circumcenter
Definition
 The point where the three perpendicular bisectors of a triangle meet. One of a triangle's points of concurrency.http://www.mathopenref.com/trianglecircumcenter.html
Term
 median
Definition
 A segment that connects a vertex of a triangle to the midpoint of the side opposite the vertex.
Term
 centroid
Definition
 The point where the three medians of the triangle intersect. The 'center of gravity' of the triangle http://www.mathopenref.com/trianglecentroid.html
Term
 angle bisector
Definition
 A line which cuts an angle into two equal halvesone endpoint at a vertex of the triangle and the other on another point on the triangle
