What is unique about the circumcenter?

The circumcenter of a polygon is the center of the circle that contains all the vertices of the polygon, if such a circle exists. For a triangle, it always has a unique circumcenter and thus unique circumcircle.

Do all triangles have a circumcenter?

Theorem: All triangles are cyclic, i.e. every triangle has a circumscribed circle or circumcircle. (Recall that a perpendicular bisector is a line that forms a right angle with one of the triangle’s sides and intersects that side at its midpoint.) These bisectors will intersect at a point O.

What type of triangles have a circumcenter within the triangle?

The circumcenter lies inside the triangle for acute triangles, on the hypotenuse for right triangles and lies outside the triangle for obtuse triangles. The circumcenter coincides with the midpoint of the hypotenuse if it is an isosceles right triangle.

Is circumcenter always inside triangle?

The circumcenter is not always inside the triangle. In fact, it can be outside the triangle, as in the case of an obtuse triangle, or it can fall at the midpoint of the hypotenuse of a right triangle. See the pictures below for examples of this.

Which of the following statements accurately gives the definition of the circumcenter of a triangle?

Circumcenter of triangle is the point where three perpendicular bisectors from the sides of a triangle intersect or meet. The circumcenter of a triangle is also known as the point of concurrency of a triangle.

What is circumcenter Theorem?

Any point on the perpendicular bisector of a segment is equidistant from the endpoints of the segment. Since OA=OB=OC , point O is equidistant from A , B and C . This means that there is a circle having its center at the circumcenter and passing through all three vertices of the triangle.

What does circumcenter mean in a triangle?

Definition of circumcenter : the point at which the perpendicular bisectors of the sides of a triangle intersect and which is equidistant from the three vertices.

What is the difference between circumcenter and centroid?

The centroid of a triangle is the point at which the three medians meet. The circumcenter is also the center of the circle passing through the three vertices, which circumscribes the triangle. This circle is sometimes called the circumcircle.

What is the only special triangle segment that does not have to go through a vertex?

A perpendicular bisector is a line (or segment or ray) that is perpendicular to a side of the triangle and also bisects that side of the triangle by intersecting the side at its midpoint. The perpendicular bisector may, or may NOT, pass through the vertex of the triangle.

Is it ever possible for the circumcenter to lie on the triangle itself?

The circumcenter is not always inside the triangle. In fact, it can be outside the triangle, as in the case of an obtuse triangle, or it can fall at the midpoint of the hypotenuse of a right triangle.
