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.
