Definitions
state the meaning of a term or idea and are ALWAYS
reversible.
Definition
1: Lines, rays or segments that intersect at right angles are
perpendicular. (Perpendicularity CANNOT be assumed.)
Definition
2: Congruent triangles (polygons) – all pairs of
corresponding parts are congruent.
Definition 3:
A median of a triangle is a line segment drawn from any vertex of
the triangle to the midpoint of the opposite side. (a median
divides into two congruent segments, or bisects the side to which
it is drawn)
Definition 4: An altitude of a
triangle is a line segment drawn from any vertex of the triangle
to the opposite side, extend if necessary, and perpendicular to
that side. (An altitude of a triangle forms a right <90>
angle with one of the sides.)
