Curated OER
Exploring the Hinge Theorem
Learners explore the application of Hinge Theorem. In this geometry lesson plan, students write inequalities, given two sides of a triangle. They solve problems with triangular inequalities using the proper theorem.
Curated OER
Triangle Inequality Theorems Investigation
Learners estimate and measure triangles. In this geometry activity, students identify the relationship between three sides and a triangle. They use the inequality theorem to decide if a triangle will be formed or not.
