This module contains lesson on illustrating theorems on triangle inequalities: -Exterior Angle Inequality Theorem; -Triangle Inequality Theorem; and -Hinge Theorem.
After going through this module, you are expected to: 1. investigate the relationship between the longest side and the largest angle in the triangle and vice versa; 2. investigate the relationship between the sum of any two sides and the remaining sides in a triangle; 3. illustrate theorems on triangle inequalities such as the Exterior Angle Inequality Theorem, Triangle Inequality Theorem, and Hinge Theorem with its converse; and 4. connect theorems in triangle inequalities in real-life setting.
