I WONDER - Can Triangles Have Obtuse Angles?

The video tutorial explains different types of angles and their properties. It covers acute angles, which are less than 90 degrees, and obtuse angles, which are greater than 90 degrees. The tutorial also discusses how these angles relate to triangles, defining acute triangles as those with all acute angles and obtuse triangles as those with one obtuse angle.
