Today – Monday, December 17, 2012 Q & A from Friday’s Warm up PG. 292: 1-13 Questions from HW #1 Learning Target: Use the Perpendicular Bisector to solve problems Independent practice/Check HW #1
PERPENDICULAR BISECTOR THEOREM: If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.
CONVERSE OF THE PERPENDICULAR BISECTOR THEOREM: If a point is equidistant from the endpoints of a segment, then it is on the perpendicular bisector of the segment.
When 3 or more lines intersect in a common point it is called concurrent. The point of intersection is called the point of concurrency. Point of concurrency
CIRCUMCENTER: CONCURRENCY OF THE PERPENDICULAR BISECTOR The perpendicular bisectors of a triangle intersect at a point that is equidistant from the vertices of the triangle.
