Angles in Two-Dimensional Figures

The video tutorial explains how angles are formed by two rays or line segments sharing an endpoint. It covers the types of angles: right, acute, and obtuse. The tutorial also describes two-dimensional figures, which have length and width but no depth. It guides viewers in identifying right, acute, and obtuse angles within a figure using a model for comparison. The lesson concludes with a summary of identifying angles in two-dimensional figures.
