CCSS What is the difference between Acute, Obtuse, Right and Straight Angles

The video tutorial explains how to classify angles into four basic types: straight, right, acute, and obtuse. It begins with an introduction to angles, describing them as two rays rotating about a fixed point called a vertex. The tutorial then delves into straight angles, which measure 180 degrees, and right angles, which measure 90 degrees. It further explores acute angles, which are less than 90 degrees, and obtuse angles, which are greater than 90 degrees but less than 180 degrees. The tutorial provides a foundational understanding of these angle types and their measurements.
