Flashcards in Chapter 4 Deck (16):

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
