The video tutorial guides viewers through constructing a triangle ABC with given angles and a side. It starts with drawing a base line of 5.8 cm, followed by constructing a 60-degree angle at point A and a 30-degree angle at point B using a compass. The intersection of these lines forms point C, completing the triangle. The video concludes by verifying the angles and confirming that triangle ABC is a right-angled triangle.
