The perpendicularbisectore of a triangle intersect at point that is equidistant from the vertices of triangle.
The angle bisectors of a triangle intersect a point that is equidistant from the sides of the triangle
The medians of a triangle intersect at a point that is distance from each vertex to the midpoint of the opposite side. If P is the centroid of triangle ABV, then
AP = 2/3 AD, BP = 2/3BF
And CP = 2/3 CE
A company plans to build a distribution center that is convenient to three of its major clients. The planners start by roughly locating the three clients ona sketch and finding the circumcenter of the triangle formed
a. Explain why using the cir cumcenter as the location center would be convenient for all the clients.
b. Make a sketch of the triangle formed by the clients. Locate the circumcenter of the triangle. Tell what segment are congruent.
