Triangle Segments Flashcards
(10 cards)
Perpendicular Bisector
intersects a side of a triangle at a 90 degree angle
Circumcenter
(perpendicular bisector)
a point equidistant from each vertex of the triangle
Median
a segment from a midpoint of a triangle side to the vertex opposite from it
Centroid
(median)
two-thirds the distance from each vertex to the opposite side’s midpoint
balancing point of the triangle
Angle Bisector
divides an angle of a triangle into two congruent angles
Incenter
(angle bisector)
equidistant from each side of the triangle
Altitudes
perpendicular segments from a vertex to a point on the opposite side or a line that contains the opposite side of the vertex
Orthocenter
(angle bisectors)
no special properties
Isosceles Triangles + Special Segments
the line of symmetry is also all of the special segments
Equilateral Triangles + Special Segments
all special segments and points of congruency coincide
