  1. Classifying Triangles Free powerpoints at http://www.worldofteaching.com Geometry

  2. Student Expectation 6th Grade: 6.3.6B Identify relationships involving angles in triangles and quadrilaterals. 7th Grade: 7.3.6B Use properties to classify triangles and quadrilaterals. Geometry

  3. Two Ways to Classify Triangles • By Their Sides • By Their Angles Geometry

  4. Classifying Triangles By Their Sides • Scalene • Isosceles Geometry

  5. Scalene Triangles • No sides are the same length Geometry

  6. Isosceles Triangles • At least two sides are the same length Geometry

  7. Classifying Triangles By Their Angles • Acute • Right • Obtuse Geometry

  8. Acute Triangles • Acute triangles have three acute angles Geometry

  9. Right Triangles • Right triangles have one right angle Geometry

  10. Obtuse Triangles • Obtuse triangles have one obtuse angle Geometry
