This graphic organizer helps students to classify triangles by both side length and angle measure. The students use different colors to vividly display various side lengths and angle measures and whether they are the same or different.

I had my students use a different color for the Right Angle measurements than I used in the sample because I felt that the green and blue were too similar. Other than that though, the graphic organizer serves as a way for students to organize the similarities and differences between each classification.
