Triangle Inequality Theorem: Determining if Angles and Side Measures Form a Triangle

The video tutorial explains how to determine if given angle or side measurements can form a triangle. It covers the Triangle Sum Theorem and its converse, demonstrating how to verify if three angles can form a triangle. The Triangle Inequality Theorem is also discussed, showing how to check if three side lengths can form a triangle using inequalities. Examples are provided to illustrate these concepts.
