  1. Chapter 5 - Relationships within Triangles

  2. B C F D E A Lesson 3-1: Triangle Fundamentals Median - Special Segment of Triangle Definition: A segment from the vertex of the triangle to the midpoint of the opposite side. Since there are three vertices, there are three medians. In the figure C, E and F are the midpoints of the sides of the triangle.

  3. B B F F D I A D K A Altitude - Special Segment of Triangle Lesson 3-1: Triangle Fundamentals The perpendicular segment from a vertex of the triangle to the segment that contains the opposite side. Definition: In a right triangle, two of the altitudes are the legs of the triangle. In an obtuse triangle, two of the altitudes are outside of the triangle.

  4. P M Q O R N L D C Perpendicular Bisector – Special Segment of a triangle Lesson 3-1: Triangle Fundamentals A line (or ray or segment) that is perpendicular to a segment at its midpoint. Definition: The perpendicular bisector does not have to start from a vertex! Example: A E A B B In the isosceles ∆POQ, is the perpendicular bisector. In the scalene ∆CDE, is the perpendicular bisector. In the right ∆MLN, is the perpendicular bisector.
