Circumcenter and Incenter Lab

Step 1: For each set of coordinates, classify triangle ABC by its sides AND angles on your worksheet. Step 2: Find the circumcenter (D) AND incenter (E) of triangle ABC. Step 3: Write down the coordinates for each point of concurrency next to its classification. Hint: Find the coordinates of the circumcenter for all three triangles first. Then, click the reset button and find the coordinates of the incenters of all three triangles. A circumcenter is the intersection of the perpendicular bisectors of the sides of a triangle. An incenter is the intersection of the angle bisectors in a triangle.
