Geometry Triangles What Am I ? First a few definitions; Triangles all have three sides, but when you consider other factors there are a variety of types. Each type of triangle can be classified by its characteristics. Whether the triangle is Scalene, or Isosceles, or Equilateral, or Acute, or Right, or Obtuse is dependent on the kind of angles and sides it has. Look at the sketches below and see if you can write good definitions for each type of triangle. Add the definitions to your glossary. Right Triangles Acute Triangles Obtuse Triangles Scalene Triangles Isosceles Triangles Equilateral Triangles Triangles Classify.doc 1 revised:10/31/2006 Triangle Relationships Here is a graphic organizer that should help you classify Triangles by their characteristics. Complete the NAMES in each triangle and complete phrases in the boxes to help show the properties of the Triangles.
