Perpendicular bisector

A line that is perpendicular to a segment at its midpoint.

Orthocenter

The point of concurrency of the altitudes of a triangle(can be inside, outside or on border of the triangle)

Centroid

The point of concurrency of the medians of a triangle(always inside triangle and divides each median into segments whose ratio is (2:1)

CPCTC (Corresponding Parts of Congruent Triangles are Congruent)

Used as a justification in a proof after you have proven two triangles congruent.

point of concurrency

a point where the altitudes, perpendicular bisectors, medians, or angles bisectors of a triangle meet

angle bisector

a ray that divides an angle into two congruent angles

Median

a segment that joins a vertex of a triangle to the midpoint of the opposite side

Altitude

a segment that joins a vertex of a triangle to the opposite side AND is perpendicular to the opposite side

equidstant

equally distant

incenter

the point of concurrency of the angle bisectors of a triangle(always in triangle)

Circumcenter

the point of concurrency of the perpendicular bisectors of a triangle(can be inside, outside, or on the border of a triangle)
