Unique Area of Triangle Formula

In summary, the Unique Area of Triangle Formula is a mathematical equation used to calculate the area of a triangle based on its side lengths and angles. It is denoted as A = 1/2 * base * height or A = 1/2 * a * b * sin(C), where a and b are two sides of the triangle and C is the angle between them. To use the formula, you need to know at least two side lengths and an angle of the triangle, and make sure the units of measurement are the same. The formula is useful in various fields, such as construction, engineering, and architecture, and has real-world applications in designing structures, surveying, navigation, and solving problems in physics and other scientific fields

Yes, it is correct. The proof involves some linear algebra, and, in particular, determinants. What is your background in that topic ?

My math background is not deep enough to understand linear algebra, much less proof at that level. This formula is so useful and cool.
