perpendicular bisector of it is equidistant from both B and C. Thus, PA = PB = PC, and so A, B, and C all lie on a circle with center P and radius PA. Conversely, suppose is circumscribed by a circle with center P and radius r. Since P is equidistant from A and B, it is on the perpendicular bisector of . Similarly, P is on the perpendicular
Perpendicular Bisector theorem. The set (or the locus) of all points equidistant from two fixed points A and B is the perpendicular bisector of segment AB. Proof. ( ) Suppose that C is equidistant from A & B. Then CA CBÊœ & ABC is isosceles, It follows from the isosceles triangle theorem,˜ case IV that the perpendicular of AB passes through C.
Perpendicular Bisector Theorem The Perpendicular Bisector Theorem states that any point on the perpendicular bisector is equidistant from the segment's endpoints. Let T be on the perpendicular bisector, RS, below. Since RS is perpendicular to PQ, △PST and △QST are both right triangles.
Bisector Thm., A, B, and C are on the same line, namely the ' bisector of PQ. 14. Since X is on the bisector of /BCN and the bisector of /CBM, X is equidistant from the sides BM), BC), CN) (/ Bisector Thm.). Therefore X is equidistant from AM) (containing BM)) and AN) (containing CN)), the QR 6MN, QS LN RS LM 7 sides of /A. By the Conv. of the ...
(Extra Credit): If the bisector of an angle in a triangle meets the opposite side at its midpoint, then the triangle is isosceles. 7. A point is on the perpendicular bisector of a line segment if and only if it lies the same distance from the two endpoints.
