Geometry (Class 37)
Overview
§5.4 (Txt. p.287) Midsegment Theorem
§5.5 (Txt. p.295) Inequalities in One Triangle
Today we focus on constructing triangles. The key question that we need to answer is: “How can you determine if it is possible to construct a triangle when you are given three segments?”
In addition, we examine an interesting property of the midpoints connecting adjacent sides of a trianlge.
