plane- a flat, 2 dimensional object, continues infinitely in all directions and has no thickness, can be defined as 2 intersecting lines or 3 non-collinear points.
perpendicular- 2 lines intersecting at a right angle
line- a 2 dimensional object with no endpoints and extends on forever in a plane, formed of infinite points.
line segment-
A line segment is the portion of a line lying strictly between two points. It has a finite length and no width.
|
ray- a one dimensional figure that consists of one endpoint A, and point B, with all point in a line of A and B
angle- a measure of degrees
median- a segment connecting any vertex of a triangle to the midpoint of the opposite side
altitude- altitude of a triangle is a line segment connecting vertex to the line containing the opposite side and the side perpendicular to that
median- a segment connecting any vertex of a triangle to the midpoint of the opposite side
