The video tutorial explains the properties of special right triangles, specifically the 30-60-90 triangle. It covers the relationships between the sides, where the short leg is denoted as X, the hypotenuse as 2X, and the long leg as X times the square root of 3. The tutorial demonstrates how to calculate the sides of the triangle using these relationships, emphasizing the importance of understanding these properties rather than memorizing the derivation process. The video concludes with practical examples of finding the short leg and hypotenuse from the long leg.
