Front

A line, segment, or ray that divides a segment into two equal parts and is perpendicular to the segment

Back

perpendicular bisector

Front

Back

angle bisector

Front

Back

median

Front

A segment that connects a vertex of a triangle to the opposite side so that it is perpendicular to that side

Back

altitude

Front

The point at which the three perpendicular bisectors intersect in a triangle.

Back

circumcenter

Front

The point at which three angle bisectors intersect in a triangle

Back

incenter
