Final Jeopardy

Congruent Triangles for 100

Name all postulates that can be used to prove triangles are congruent.

ASA, SAS, SSS, HL, AAS

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.
