Understanding Plane Figures

This video tutorial introduces the concept of 'bangun datar', a flat shape bounded by straight lines. It covers various types of bangun datar, including squares, rectangles, and triangles, and explains key components such as sides (sisi), angles (sudut), and vertices (titik sudut). The video provides examples, particularly focusing on squares and triangles, to illustrate how to count these components. The tutorial concludes with a summary of the discussed concepts, aiming to enhance understanding of basic geometric shapes.
