Curated OER
The Ambiguous Case
Students investigate the relationship of triangles with its sides and angles. In this geometry lesson, students create visual on the graphing navigator as they study triangles. They move the sides around to create different angle-side...
Curated OER
Corresponding Parts of Similar Triangles
Here is a lesson that has learners take a look at corresponding parts of similar triangles, ratios of similarity, reductions and enlargements. They'll manipulate the scale factor (r) to observe the changes in similar triangles and then...
Curated OER
Angle-Side Relationships
Young scholars investigate triangles and their angle-side relationship. In this geometry lesson plan, students identify the property of the triangles and use it to solve the problem correctly. They use the TI to graph their triangles.
