The document discusses geometric properties of triangles. It presents six statements about circumcenters, centroids, altitudes, and orthocenters and asks the reader to identify whether each statement is true or false. The statements concern the definitions and locations of these special points relative to triangles.

1. Opener: Start by the time the bell rings.
Decide whether each of the following statements is true or false. If it is false, please note
how you would change the statement to make it true.
TRUE FALSE A circumcenter is equidistant from the sides of a triangle.
TRUE FALSE A centroid is the point of concurrency of the altitudes of the triangle.
TRUE FALSE Altitudes form the incenter of a triangle.
TRUE FALSE Orthocenters are inside all types of triangles.
