1

Exterior Angle Theorem

The measure of an exterior angle is equal to the sum of the measures of the 2 remote interior angles

2

Congruent Polygons

polygons with congruent corresponding sides and congruent corresponding angles

3

Congruency Statement

statement showing corresponding angles and sides are congruent

4

Two polygons are congruent if and ONLY if their corresponding ____ and _____ are congruent

angles and sides

5

CPCTC

corresponding parts of corresponding triangles are congruent

6

Third Angle Theorem

If 2 angles of a triangle are congruent to two angles of another triangle, the 3rd angles are congruent

7

Isosceles Triangle Theorem

If two sides of a triangle are congruent, the angles opposite those sides are also congruent

8

Converse Isosceles Triangle Theorem

If 2 angles of a triangle are congruent, the sides opposite those angles are also congruent.

9

Included Angle

The angle formed by 2 adjacent sides of a polygon

10

Included side

Side formed by connecting 2 consecutive vertices

11

Side Side Side (SSS)

If 3 sides of a triangle are congruent to 3 sides of another triangle, the sides are congruent

12

Side Angle Side (SAS)

If 2 sides and the included angle of one triangle are congruent to 2 sides and the included angle of another triangle, they are congruentfw l

13

Triangle Angle-Sum Theorem

The sum of the measures of the angles of a triangle is 180 degrees

14

Angle Side Angle (ASA)

If two angles and the included side of one triangle is congruent to two angles and the included side of another, the triangles are congruent

15

Angle-Angle Side (AAS)

If 2 angles and a nonincluded side of one triangle are congruent to 2 angles and a nonincluded side of another, the triangles are congruent

16

Hypotenuse-Leg Congruence Theorem

If the hypotenuse and leg of one triangle are congruent to the hypotenuse and leg of another right triangle, they are congruent
