How Many Unique Triangles | 7.G.A.2

The video tutorial explores the concept of unique triangles formed by given angle measures. It presents a problem involving three angles: 50°, 50°, and 100°, and asks how many unique triangles can be formed. The video explains that for any three angles to form a triangle, their sum must be 180°. Since the given angles sum to 200°, no triangle can be formed. The tutorial concludes by reinforcing the understanding of triangle angle sum properties.
