Definition--Geometry Basics--Circumcenter of a Triangle | Circumcenter of a TriangleTopicGeometry Basics DefinitionThe point where the perpendicular bisectors of a triangle intersect. DescriptionThe circumcenter of a triangle is the point where the perpendicular bisectors of the sides of the triangle intersect. This point is equidistant from all three vertices of the triangle. Understanding the circumcenter is important in solving problems related to triangle geometry and circle properties. For example, the circumcenter is the center of the circumscribed circle that passes through all three vertices of the triangle. |

In this program we explore the properties of circles. We do this in the context of two real-world applications. In the first, we look at the design of the Roman Coliseum and explore how circular shapes could have been used to design this elliptical structure. In the second application we look at the Roman Pantheon, specifically its spherical dome, to see how the properties of chords and secants help clarify its unique design. |
