Circumcircle
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.
