1 5.3 Medians and Altitudes of a Triangle Goal: Use properties of medians of a triangle and use properties of altitudes of a triangle

2 Standard 16.0 Students perform basic constructions with a straightedge and compass, such as angle bisectors, perpendicular bisectors, and the line parallel to a given line through a point off the line. Los estudiantes realizan construcciones básicas con una regla y un compás, tales como la bisectriz de un ángulo, las bisectrices de los segmentos perpendiculares, y la línea paralela a una línea dada a través de un punto afuera de la línea.

3 Definitions A median of a triangle is a segment whose endpoints are a vertex of the triangle and the midpoint of the opposite side. The point of concurrency of the three medians of a triangle is called the centroid of the triangle. The three medians of a triangle are concurrent. An altitude of a triangle is the perpendicular segment from a vertex to the opposite side or to the line that contains the opposite side. The lines containing the three altitudes are congruent and meet at a point called the orthocenter of a triangle

4 Theorem 5.7 Concurrency of Medians of a Triangle The medians of a triangle are congruent at a point that is two thirds of the distance from each vertex to the midpoint of the opposite side

5 Theorem 5.8 Concurrency of Altitudes of a Triangle The lines containing the altitudes of a triangle are concurrent
