Triangle Construction Techniques

This video tutorial demonstrates how to construct a side-angle-side (SAS) triangle. It begins with an introduction to SAS triangles, followed by a list of necessary tools: a pencil, ruler, and protractor. The tutorial then provides step-by-step instructions for drawing the base line, constructing a 65° angle, and completing the triangle by drawing the final side. The video emphasizes accuracy in measurement and alignment to ensure a precise construction.
