One Two or No Triangle?

The video tutorial explores the properties of triangles, focusing on angles and side lengths. It explains how to determine the height of a triangle using trigonometry, specifically the sine function. The tutorial discusses conditions under which a triangle can exist based on its side lengths and height. It also examines the possibility of multiple triangles existing when rotating a triangle, concluding that only one triangle can exist under certain conditions.
