Understanding Angles in Geometry

This video tutorial explores the differences between acute, right, and obtuse angles. It begins with an introduction to these types of angles, followed by detailed explanations of each. The tutorial covers how to identify acute angles as those less than 90 degrees, right angles as exactly 90 degrees, and obtuse angles as more than 90 degrees. The video concludes with practical applications, showing how understanding these angles helps in identifying various shapes.
