The Obtuse Triangle has an obtuse angle (an obtuse angle has more than 90°). In the picture on the left, the shaded angle is the obtuse angle that distinguishes this triangle. Since the total degrees in any triangle is 180°, an obtuse triangle can only have one angle that measures more than 90°.
ARI Curriculum Companion – Working with Polygons Virginia Department of Education 12 Name: Triangle Classification . Measure each of the angles in each triangle using a protractor. Extend the sides if necessary. Make sure that the measures of the three angles add up to 180°. Record your answers in the Triangle Classification Table.
Triangles don’t need to be tricky for your students! This week, my class tackled classifying triangles and really enjoyed the whole process. The recipe for success involved some triangle foldables, interactive notebooks, an easy-to-follow anchor chart, and some practice. First, we added some mini triangle classification charts from my 2-Dimensional Foldables Packet to our […]
It's important for you to know that triangles aren't just a part of math! One at a time, you and your partner can choose a real world triangle off the back table. Then, you'll use your tools, such as a protractor, square corner, or ruler to classify each triangle. Make sure you record Triangle #1 next to number one on your recording sheet.

Triangle Classification. The basic elements of any triangle are its sides and angles. Triangles are classified depending on relative sizes of their elements. As regard their sides, triangles may be. Scalene (all sides are different) Isosceles (two sides are equal) Equilateral (all three sides are equal) And as regard their angles, triangles may be
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.
