Let's explore. 1.) Change the shape of the triangle and then check the three boxes below. What do you observe? 2.) Move the vertices of the triangle. Are your observations in 1 still true? 3.) Make a conjecture about your observations.
In any triangle, a circle called circumcircle may be drawn through its vertices. The center of the circumcircle is called circumcenter is the intersection of the perpendicular bisectors.
