A simple sum for simplices

Christian Aebi, Grant Cairns

We give a vector identity for $n + 2$ points in $R^{n}$ . It follows as a corollary that when $n$ is odd the sum of the signed volumes of the $n$ -simplices is zero, and when $n$ …

Lattice equable quadrilaterals II -- kites, trapezoids and cyclic quadrilaterals

Christian Aebi, Grant Cairns

We show that there are 4 infinite families of lattice equable kites, given by corresponding Pell or Pell-like equations, but up to Euclidean motions, there are exactly 5 lattice eq…
