Triangle Line Segments and Centers

Covers the four main types of triangle line segments (Perpendicular Bisector, Angle Bisector, Altitude, and Median) and the points where they intersect (Circumcenter, Incenter, Orthocenter, and Centroid). Helps memorize what each line does and which center it creates.

Perpendicular Bisector

Forms right angles at midpoint of triangle's sides (bisecting the sides)

Circumcenter

Intersection point of perpendicular bisectors

Angle Bisector

Forms pairs of congruent angles at triangle's vertices (bisecting the angles)

Incenter

Intersection point of angle bisectors

Altitude

Extends from triangle’s vertices forming right angles at opposite sides

Orthocenter

Intersection point of altitudes

Median

Extends from triangle’s vertices to midpoints of opposite side

Centroid

Intersection point of median
