Get out your notes from Friday over 8.1-8.3. We will go over all 3 lessons and you will have classwork/homework over this!

8.1 Perpendicular Bisectors of Triangles Essential Question: How can you use perpendicular bisectors to find the point that is equidistant from all the vertices of a triangle?

Circumscribed circle(circumcircle)- every vertex of the polygon lies on the circle Circumcenter-the point of concurrency of the three perpendicular bisectors of a triangle In the figure, circle C is circumscribed about XYZ. Circle C is called the circumcircle of the triangle.

Concurrent- three or more lines that intersect at one point Point of concurrency- a point where three or more lines coincide
