WebThe circumcircle of a triangle is the unique circle determined by the three vertices of the triangle. Its center is called the circumcenter (blue point) and is the point where the (blue) perpendicular bisectors of the sides of the triangle intersect.

WebThe incircle of a triangle ABC is a circle that is tangent to all three sides of the triangle. Its center, the incenter of the triangle, lies at the point where the three internal angle bisectors of the triangle cross each other. The nine-point circle is … WebSal kind of skips the normal first step of starting at a vertex and drawing a circle, then drawing two congruent circles whose intersection would be equidistant from the two points. Sal avoids the first step by drawing two congruent circles whose radii are equidistant from the vertex. Does this help, or you need more explanation? 2 comments
