Relations between Inradius, circumradius and exradii (Registration Closed)
|When:||April 13, 2019, 3:30pm – 5:30 pm|
|Where:||NYU Courant Institute, 251 Mercer St (map). Room 101.|
There are well-known formulas for the inradius, circumradius, and exradii of a triangle. Relationships between these quantities are less familiar. In this presentation, various approaches to some of these less widely known relationships and ideas will be considered.
Please share this invitation with your colleagues! Note that this workshop is free, but registration is required as we expect to reach capacity.
