Medians, Altitudes, and Perpendicular Bisectors
• Understanding about the properties of medians, altitudes, and perpendicular ( |_) bisectors.
Lesson 4-3 Medians, Altitudes, and Perpendicular Bisectors
Median: A segment from a vertex to the midpoint of the opposite side
Altitude: The perpendicular segment from a vertex to the line that contains the opposite side.
In an acute triangle all of the altitudes are all inside the triangle.
In a right triangle, two of the altitudes are the legs of the triangle and the third is inside the triangle.
In an obtuse triangle, two of the altitudes are outside of the triangle.
Perpendicular Bisector: a line (or ray or segment) that is perpendicular to the segment at its midpoint.
