Triangle Area and Dimensions

The video tutorial explains how to calculate the area of triangles by identifying a base and corresponding height, without using a calculator. It covers the calculation of two triangles, A and B, using different base-height pairs to demonstrate that the area remains consistent regardless of the chosen base-height pair. The formula for the area of a triangle, which is half the product of its base and height, is applied to both triangles, showing the process step-by-step.
