The video tutorial explores the geometric problem of fitting a square within a triangle using a compass and straightedge. It begins by discussing the conditions under which a square can be constructed, then explores the use of rectangles to approximate a square. The tutorial demonstrates graphical methods and constructions, including forcing a square and using similar triangles. It concludes with alternative methods and a discussion on the centroid of a triangle.

What is the initial problem discussed in the video?

• Constructing a square inside a triangle

• Constructing a rectangle inside a triangle

• Constructing a triangle inside a square

• Constructing a circle inside a triangle

What is the purpose of plotting the height and width of rectangles?

• To identify the intersection point that forms a square

• To calculate the diagonal of the square
