Why are the alternate interior angles, the alternate exterior angles, and the corresponding angles equal in this model? - Since the shape is a parallelogram the transversal must cross two parallel lines. - Since the shape is a parallelogram the transversal must cross two perpendicular lines. - The angles are not equal they are all supplementary. 5.

To address the question, let's focus on the first three parts as per the guidelines:

3. Using $CD$ as the transversal, which angles are considered alternate exterior angles?

• $\angle C A Q$ and $\angle D B O$: These angles are on opposite sides of the transversal $CD$ and outside the lines it intersects, making them alternate exterior angles.
• $\angle C A B$ and $\angle U B O$: These angles are not alternate exterior angles because they are not both outside the lines intersected by the transversal.
• $\angle Q A B$ and $\angle A B O$: These angles are not alternate exterior angles because they are not both outside the lines intersected by the transversal.
• $\angle A Q U$ and $\angle B O R$: These angles are not alternate exterior angles because they are not both outside the lines intersected by the transversal.

The answer is the first one: $\angle C A Q$ and $\angle D B O$.

4. Why are the alternate interior angles, the alternate exterior angles, and the corresponding angles equal in this model?

• Since the shape is a parallelogram the transversal must cross two parallel lines.: This is correct. In a parallelogram, opposite sides are parallel, and a transversal crossing these parallel lines creates equal alternate interior, alternate exterior, and corresponding angles.
• Since the shape is a parallelogram the transversal must cross two perpendicular lines.: This is incorrect because a parallelogram does not necessarily have perpendicular sides.
• The angles are not equal they are all supplementary.: This is incorrect in the context of parallel lines and a transversal, where alternate interior, alternate exterior, and corresponding angles are equal, not supplementary.

The answer is the first one: Since the shape is a parallelogram the transversal must cross two parallel lines.

5. Critical Thinking Problem: Which of the following segments is NOT considered a transversal?

• $CD$: This is a transversal as it is mentioned in the context of the problem.
• $QU$: This could be a transversal if it crosses two lines, but without additional context, it's unclear.
• $RO$: This could be a transversal if it crosses two lines, but without additional context, it's unclear.
• $CA$: This is likely not a transversal if it is one of the lines being intersected by the transversal $CD$.

The answer is likely $CA$, as it is not described as a transversal in the context provided.

In summary, the answers are: 3. $\angle C A Q$ and $\angle D B O$ 4. Since the shape is a parallelogram the transversal must cross two parallel lines. 5. $CA$ is not considered a transversal.
