The circumcenter is equidistant from all the vertices. _____ 14. A perpendicular bisector cuts through the midpoint of a segment. _____ 15. A median cuts through the midpoint of a segment. _____ 16. A point on an angle bisector is equidistant from two sides of the triangle _____ 17. It is possible for a median, altitude, perpendicular bisector, & angle bisector to ALL be represented by the same line in a triangle. _____ 18. No point of concurrency can ever meet outside a triangle. _____ 19. The centroid is 2/3 distance from the vertex of the median. _____ 20. Altitudes from a vertex can meet the opposite side at an angle OTHER than 90. 21.
