Question 1
Points: 1
Name the angle relationship.
Explanation
Angle 1 and Angle 2 are in the same relative position at each intersection where the transversal crosses the lines, which defines them as corresponding angles.
Question 2
Points: 1
Name the angle relationship.
Explanation
The angles are located between the two lines (interior) and on opposite sides of the transversal line (alternate), making them alternate interior angles.
Question 3
Points: 1
Name the angle relationship.
Explanation
The angles are located on the same side of the transversal and between the two lines, identifying them as consecutive interior angles.
Question 4
Points: 1
What type of angle pair is \(\angle 1\) and \(\angle 3\)?
Explanation
Angle 1 and Angle 3 are in matching positions at different intersections along the same transversal, which classifies them as corresponding angles.
Question 5
Points: 1
Which pair of angles are alternate exterior angles?
Explanation
Alternate exterior angles are those on opposite sides of the transversal and outside the two lines being intersected. Angles 2 and 8 satisfy these conditions.
Question 6
Points: 1
Which lines are parallel, and why?
Explanation
The marked angles are in corresponding positions relative to lines p and q. Since they are shown as congruent, the lines p and q must be parallel according to the Converse of the Corresponding Angles Postulate.
Question 7
Points: 1
Which lines are parallel, and why?
Explanation
The congruent angles shown are alternate interior angles between lines m and n. By the Converse of the Alternate Interior Angles Theorem, lines m and n are parallel.
Question 8
Points: 1
Which lines are parallel, and why?
Explanation
The congruent angles are in alternate interior positions for lines p and q, proving that p is parallel to q.
Question 9
Points: 1
Which condition would prove \(s \parallel t\)?
Explanation
Angle 1 and the angle labeled 108 degrees are corresponding angles. If they are equal, then the lines s and t are parallel by the Converse of the Corresponding Angles Postulate.
Question 10
Points: 1
Given \(\angle 3 \cong \angle 7\), state the theorem that proves \(j \parallel k\).
Explanation
Since angles 3 and 7 are corresponding angles, their congruence proves the lines are parallel according to the Converse of the Corresponding Angles Postulate.
Question 11
Points: 1
Given \(\angle 2\) & \(\angle 5\) are supplementary, state the theorem that proves \(j \parallel k\).
Explanation
Angles 2 and 5 are consecutive interior angles. If they are supplementary, the Converse of the Consecutive Interior Angles Theorem proves the lines are parallel.
Question 12
Points: 1
Given \(\angle 1 \cong \angle 4\), is there enough information to prove \(j \parallel k\)? Explain.
Explanation
Angles 1 and 4 are vertical angles at a single intersection. While they are always congruent, this relationship does not link line j to line k and thus cannot prove them parallel.
Question 13
Points: 1
What reason is missing from this proof?
Explanation
In the context of the proof steps, the reason involves replacing one equal value with another in an equation, which is the Substitution Property.
