number - None

Properties that reference this function:

area of quadrilateral ABCD = area of quadrilateral BCDA (Area of Quadrilateral Equality)

area of quadrilateral ABCD = (area of pentagon ABCDX) + (area of △DAX) (Area of Quadrilateral)

area of pentagon ABCDE = (area of quadrilateral ABCD) + (area of △DEA) (Area of Pentagon)

area of pentagon ABCDE = (area of pentagon ABCDX) + (area of quadrilateral DEAX) (Area of Pentagon (2))

area of hexagon ABCDEF = (area of hexagon ABCDEX) + (area of quadrilateral EFAX) (Area of Hexagon)

Conditional properties that reference this function:

if ABCD is a square, then area of quadrilateral ABCD = (distance AB) ⋅ (distance AB) (link)
if m∠ABC = 180, then area of △ACD = area of quadrilateral ABCD (link)
if m∠ABC = 180, then area of quadrilateral XABC = area of △XAC (link)
