388- Explorations and Problem Solving with Heron's Formula and Alternative Proofs

Friday, April 17, 2015: 9:30 AM-10:30 AM
260 (BCEC)


Lead Speaker:
James Wilson


Mathematical reasoning and problem solving will use Heron's formula in various contexts. Illustration of a proof using complex numbers and a geometric proof using excircles and incircles will be given. Problems will explore some optimization of areas and the search for all triangles with integer sides and integer area for a fixed perimeter.
