altitude the perpendicular segment from a vertex to the opposite side or a line containing the opposite side

midsegment- the segment that connects the midpoints of two sides of a triangle midsegment

median- the segment connecting the vertex of a triangle to the midpoint of its opposite side median

Review Symmetry Line in An Isosceles Triangle Vertex Angle Bisector Conjecture: In an isosceles triangle, the bisector of the vertex angle is also a median and an altitude. bisector median altitude 12 A B C D

Objective Students will learn the definitions of special quadrilaterals and explore the sum of exterior angles of a polygon. Students will take notes, do an investigation and apply properties to solve problems.
