Area Of Triangles: Calculating the area of a different triangles

The video tutorial explains how to calculate the area of a triangle using the formula: area = 1/2 * base * height. It provides examples with different triangle dimensions, emphasizing the importance of using the vertical height rather than the slant height. The tutorial also includes a demonstration with an upside-down triangle, reinforcing the consistent application of the formula across various triangle orientations.
