3.2 - Types of TrianglesIn this mini unit, you will focus on explore the properties of triangles using geometric tools, such as the distance formula and slope. Triangles are the strongest shape, so they are used in structures across the world. The skills learned in this section help engineers, architectures and interior decorators as they include this shape in their designs.
1. Download and print the challenge problem to the right as a warm-up. Once challenge is complete, see instructor for answer key.

Objectives
Learning: I will use coordinate representations of geometric ideas such as distance, slope and midpoint to classify quadrilaterals. Language: Students will match definitions to names of triangles then draw examples of each of the triangles making sure to use the correct symbols. |

2. Review your knowledge of the different types of triangles by playing the game below, then download, print and complete the Triangles Recall worksheet. This knowledge will be used as you identify different types of triangles as they are drawn on a coordinate grid.
After clicking on the pic above, make sure you select WITH ROTATION level as that is how you will see the triangles throughout this mini unit.

3. After watching the video to the left, complete the following practice problems by downloading and printing the Identifying Triangles worksheet. Make sure you read the questions all the way through the questions and understand what it is asking you to do.
HINT: When plotting triangles on your worksheet, make sure to include the name of the points.

4. Create a comic (follow the link below) that represents the method you follow or an example on how to identify triangles in a coordinate plane. I created an example of a comic but I challenge you to create your own comic that is better than mine. If you make a more thorough and exact comic, I'll replace mine with yours on this website.
