  2. Congruent Triangles for 100 Name all postulates that can be used to prove triangles are congruent. ASA, SAS, SSS, HL, AAS

  3. Congruent Triangles for 200 ____________________ extend from a vertex of a triangle and are perpendicular to the opposite side. ____________________ extend from a vertex of a triangle to the midpoint of the opposite side. There are three interior altitudes in a/an ____________________ triangle. In a/an ____________________ triangle, one altitude is interior and the other two are the sides of the triangle. There is one interior altitude and two exterior altitudes in a/an _______________ triangle. A __________________________ is both a median and an altitude. The ____________________ of a right triangle is always the longest side. Altitudes Medians acute right obtuse perpendicular bisector hypotenuse
