### Example Question #1 : How To Find Out If Lines Are Parallel

Which answer contains all the angles (other than itself) that are congruent to Angle 1?

**Possible Answers:**

Angles 2 and 4

Angles 8 and 6

Angles 2 and 5

Angles 4 and 5

Angles 4, 5, and 8

**Correct answer:**

Angles 4, 5, and 8

Because of the Corresponding Angles Theorem (Angle 2 and Angle 5), Alternate Exterior Angles (Angle 2 and Angle 8), and Vertical Angles (Angle 2 and Angle 4).

### Example Question #1 : Parallel Lines

Angles 2 and 3 are congruent based on which Theorem?

**Possible Answers:**

Consecutie Internior Angles

Alternate Exteriors Angles

Corresponding Angles

Vertical Angles

Alternate Interior Angles

**Correct answer:**

Vertical Angles

Veritcal angles means that the angles share the same vertex. Angles 2 and 3 are a vertical pair of angles, which mean that they are congruent.

### Example Question #1 : How To Find Out If Lines Are Parallel

If angles 2 and 6 are congruent, lines AB and CD are parallel based on which theorem?

**Possible Answers:**

Corresponding Angles

Alternate Exterior Angles

Vertical Angles

Alternate Interior Angles

Consecutive Interior Angles

**Correct answer:**

Corresponding Angles

Angles 2 and 6 are Corresponding Angles. If each of the set of angles were taken separately, angels 2 and 6 would occupy the same place and are thus corresponding angles.

### Example Question #1 : Parallel Lines

What is the sum of Angle 3 and Angle 5?

**Possible Answers:**

180 deg

45 deg

15 deg

360 deg

90 deg

**Correct answer:**

180 deg

Because of the Consecutive Interior Angle theorem, the sum of Angles 3 and 5 would be 180 deg.

### Example Question #1 : Parallel Lines

If lines AB and CD are parallel, angles 1 and 8 are congruent based on which theorem?

**Possible Answers:**

Vertical Angles

Corresponding Angles

Alternate Exterior Angles

Consecutive Interior Angles

Alternate Interior Angles

**Correct answer:**

Alternate Exterior Angles

Angles 1 and 8 are on the exterior of the parallel lines and are on opposite sides of the transversal. This means the Theorem is the Alternate Exterior Angle theorem.

### Example Question #1 : How To Find Out If Lines Are Parallel

If Angles 2 and 7 are congruent, line AB and CD are __________.

**Possible Answers:**

skew

askance

parallel

perpendicular

**Correct answer:**

parallel

Lines AB and CD are parallel based on the Alternate Exterior Angle theorem.

### Example Question #1 : Parallel Lines

If lines AB and CD are parallel, angles 5 and 1 are __________.

**Possible Answers:**

exterior angles

corresponding angles

alternate interior angles

interior angles

alternate exterior angles

**Correct answer:**

corresponding angles

If the two lines are parallel, the transverse line makes it so that angles 2 and 7 are corresponding angles.

### Example Question #1 : Parallel Lines

If lines AB and CD are parallel, the sum of Angle 6 plus Ange 4 equals __________.

**Possible Answers:**

90 deg

45 deg

180 deg

15 deg

0 deg

**Correct answer:**

180 deg

If lines AB and CD are parallel, the sum of Angles 4 and 6 is 180 deg based on the Consecutive Interior Angle Theorem.

### Example Question #1 : How To Find Out If Lines Are Parallel

If lines AB and CD are parallel, angles 2 and 7 are congruent based on which theorem?

**Possible Answers:**

There is not enough information to determine

Alternate Interior Angles

Alternate Exterior Angles

Corresponding Angles

Consecutive Angles

**Correct answer:**

Alternate Exterior Angles

Angles 2 and 7 are both on the exterior side of the transverse, this means they are Alternate Exterior Angles.

### Example Question #1 : How To Find Out If Lines Are Parallel

If lines AB and CD are parallel, which angles are congruent to Angle 3?

**Possible Answers:**

Angles 7 and 6

Angles 1 and 5

Angles 2, 7, and 6

Angles 5, 8, and 1

There is not enought information to determine

**Correct answer:**

Angles 2, 7, and 6

Angle 2 is congruent based on the Vertical Angle Theorem. Angle 7 is congruent based on the Corresponding Angles Theorem. Angle 6 is congruent based on the Alternate Interior Angles theorem.
