Chapter 4
Postulates/ Theorems
Theorem 4.1 â Triangle Sum Theorem
The sum of the measures of the interior angles of a triangle is 180ï°
Theorem 4.2 â Exterior Angle Theorem
The measure of an exterior angle of a triangle is equal to the sum
of the measures of the two nonadjacent interior angles
Corollary to the Triangle Sum Theorem
The acute angles of a right triangle are complementary
Theorem 4.3 â Third Angles Theorem
If two angles of one triangle are congruent to two
triangles of another triangle, then the third angles
are also congruent.
