11.8 Hero's and Brahmagupta's Formulas

Section 11.8 was about Hero's and Brahmagupta's Formulas. Also, we learned an equation for the area of a triangle when SAS is given. 

SAS

Hero's Formula-(for area of triangles)

                                                  
                     

where a, b, and c are the side lengths









Brahmagupta's Formula-(for CYCLIC quadrilaterals ONLY)

where a, b, c, and d are the side lengths

Well, Hero and Brahmagupta were math geniuses, but they will never be able to top the great Mr. Wilhelm.
