Triangles

A triangle is one of the basic shapes in geometry. In this unit, students investigate the relationship among the sides and between the sides and angles of a given triangle including special segments such as median and altitude. They also investigate conditions necessary to have congruent triangles, use appropriate notation to describe two congruent triangles, and examine theorems that establish congruency between two triangles.
