Triangles - Geometry (7th grade)

Exploring Triangles in 6th and 7th grade - Part 1, 2, 3, 4

Exploring Triangles (7th grade)   Three lines in a plane, no two parallel, intersect in exactly 3 points. Three points in a plane, not all on a single line, define three unique sides of a triangle. These points are called the vertices of the triangle. The vertices are usually labelled with capital letters and the oppposite sides with the corresponding lower case letters. The interior angles are labelled by naming a sequence of vertices or with lower case Greek letters.  This is another FREE GEOMETRY PRINTABLE presented to you from the Geometry section of K12math.com
