PPT-6-1 Medians Objective: To identify and construct medians in triangles

February 2011 Fellow Brooke Odle Teacher Ms Sanchez Saint Vincent Academy Lesson Overview Introduce topic Vocabulary and Theorem 61 Example Problems Real World Application Electrocardiograms. Comparison of Raised Medians and Two-Way Left-Turn Lanes Because raised medians are the most restrictive access management treatment, building a raised median along an arterial is often very controway Median of a Triangle. A line segment connecting a vertex of a triangle to the midpoint of the opposite side. On a piece of graph paper, graph the triangle with vertices A(2, 1) B(5, 8) C(8, 3). . Find the midpoint of each side and label the midpoint opposite A “D”, opposite B “E”, opposite C “F”. . Talya Eden, . Tel Aviv . University. Amit Levi, . University of Waterloo. Dana . Ron, .

If triangles are similar are other things similar as well. Proportional Parts Conjecture. If two triangles are similar, then the length of the corresponding altitudes, medians, and angle bisectors are proportional to the lengths of the corresponding sides. This shows similar Triangles.

So, if you can prove the two triangles are congruent then you know their corresponding parts must be congruent as well.. ?. . (0,1.6). 3. Solve for x. x=3. x=5.
