Mathematics of TV Measurements

The video tutorial explains how to determine the maximum size of a TV that can fit into a cabinet by considering the cabinet's dimensions and the need for edging space. It uses the Pythagorean theorem to calculate the diagonal length of the TV, which is the standard measurement for TV sizes. The process involves subtracting the edging space from the cabinet dimensions to find the TV's width and height, then applying the theorem to find the diagonal. Finally, the diagonal length is rounded to the nearest tenth.

How are TV screens typically measured?

• By their width

• By their height

• By their circumference

• By their diagonal
