5.5: Concurrent Lines, Medians, and Altitudes Flashcards
Concurrent
Three or more lines intersect at one point.
Point of Concurrency
The point at where they intersect.
Circumcenter of the Triangle
The point of concurrency of the perpendicular bisectors of a triangle.
Circumscribed About
A circle is drawn connecting the vertices of a polygon.
Incenter of the Triangle
The point of concurrency of the angle bisectors of a triangle.
Inscribed in
A circle is drawn connecting the points equidistant from the center of the bisectors.
Median of a Triangle
A segment whose endpoints are a vertex and the midpoint of the opposite side.
Centroid
The point of concurrency of the medians.
Altitude of a Triangle
The perpendicular segment from a vertex to the line containing the opposite side.
Orthocenter of a Triangle
The lines containing the altitudes of a triangle are concurrent at the orthocenter.
