## What is inductive vs deductive reasoning?

### Inductive reasoning it reaching conclusions based on onservations and deductive reasoning is using logic, facts, and general principles to reach indisputable conclusions.

1

## What are Vertical Angles?

### Pairs of angles formed by intersecting lines that are not adjacent.

2

## What is a transversal?

### A line that intersects two coplanar lines at different points.

3

## What are corresponding angles?

###
Pairs of angles formed by a transversal that:

1. Have different vertices

2. One is interior and one is exterior

3. On the same side of the transversal

4

## What are Alternate Interior angles?

###
Pairs of angles formed by a transversal that:

1. Have different vertices

2. Are interior angles

3. Are not on the same side of a transversal

5

## What are same-side interior angles?

###
Pairs of angles formed by a transversal that:

1. Have different vertices

2. Both are interior angles

3. On the same side of a transversal

6

## What are alternate exterior angles?

###
Pairs of angles formed by a transversal that:

1. Have different vertices

2. Both are exterior angles

3. On different sides of the transversal

7

## What are remote interior angles?

### In a triangle, the interior angles that are nonadjacent to a given exterior angle.

8

## What is the parallel postulate?

### Given any line and a point not on the line, there is a line parallel to the given line through the given point.

9

## What is the Vertical Angles Theorem?

### (VAT) Vertical angles are congruent. If any angles are vertical, then they are congruent.

10

## What is the Angle Addition Postulate?

### (AAP) AVB+BVC=AVC part+part=whole

11

## What is the Segment Addition postulate?

### (SAP) The A to B and B to C is equal to the distance from A to C. Part + Part = Whole

12

## What is the Corresponding Angles Postulate?

### (CAP) If a transversal cuts two lines so that corresponding angles are congruent, then the lines are parallel.

13

## What is the Alternate Interior Angles Theorem?

### (AIAT) If a transversal cuts two lines so that the alternate interior angles are congruent, then the lines are parallel.

14

## What is the Alternate Exterior Angles Theorem?

### (AEAT) If a transversal cuts two lines so that the alternate exterior angles ares congruent, then the lines are parallel.

15

## What is the Same-Side Interior Angles Theorem?

### (SSIAT) If a transversal cuts two lines so that the same-side interior angles are supplementary, then the lines are parallel.

16

## What is the Converse of Corresponding Angles Postulate?

### (CCAP) If a transversal cuts two parallel lines, the the corresponding angle pairs are congruent.

17

## What is the Converse of the Alternate Interior Angles Theorem?

### (CAIP) If a transversal cuts two parallel lines, then the alternate interior angle pairs are congruent.

18

## What is the Converse of the Alternate Exterior Angles Theorem?

### (CAEAT) If a transversal cuts two parallel lines, then the alternate exterior angle pairs are congruent.

19

## What is the Converse of the Same-Side Interior Angles Theorem?

### (CSSIAT) If a transversal cuts two parallel lines, then the same-side interior angle pairs are supplementary.

20

## What is the Triangle Exterior Angles Theorem?

### (TEAT) In any triangle, the measure of an exterior angle is equal to the sum of the measures of its remote interior angles.

21

## What is the Triangle Interior Angles Theorem?

### (TIAT) In a triangle, the sum of the measures of the interior angles is 180.
