Constructing Triangle ABC and Angles

The video tutorial from Mindset Academy guides viewers through constructing a triangle ABC with a base of 105 mm, an altitude of 35 mm, and a vertical angle of 60 degrees. The process involves drawing the base line, constructing the vertical angle, drawing a perpendicular line, bisecting the base, and finalizing the triangle. The tutorial emphasizes precise measurement and geometric construction techniques.
