    • C.

      Alternate Exterior

    • D.

      Corresponding

    Correct Answer
    B. Alternate Interior
    Explanation
    The relationship between 8 and 14 can be classified as alternate interior. This means that the two numbers are on opposite sides of a transversal line, and they are located between two other lines. In this case, the transversal line intersects two parallel lines, and 8 and 14 are located on the same side of the transversal, but on different parallel lines.

    • C.

      Alternate Exterior

    • D.

      Same Side Interior

    Correct Answer
    D. Same Side Interior
    Explanation
    The relationship between 3 and 10 is classified as "Same Side Interior". In geometry, same side interior angles are a pair of angles that are on the same side of the transversal line and inside the two parallel lines. In this case, 3 and 10 are both interior angles on the same side of the transversal line, and they are inside the two parallel lines. Therefore, they are classified as same side interior angles.

  • 4. 

    In the figure, m 2 = 92 and m 12 = 74. Find the m10 and tell which postulate or theorem you used. 

    • A.

      92; Corresponding Angles Theorem

    • B.

      92; Alternate Interior Angles Theorem

    • C.

      88; Same Side Interior Angles Theorem

    • D.

      88; Supplementary Angles Theorem

    Correct Answer
    A. 92; Corresponding Angles Theorem
    Explanation
    The Corresponding Angles Theorem states that if a transversal intersects two parallel lines, then the corresponding angles are congruent. In this case, m2 and m10 are corresponding angles because they are on the same side of the transversal and they are both formed by the intersection of the same pair of parallel lines. Since m2 is given as 92, we can conclude that m10 is also 92 based on the Corresponding Angles Theorem.

  • 5. 

    In the figure, m 2 = 92 and m 12 = 74. Find the m9 and tell which postulate or theorem you used. 

    • A.

      92; Corresponding Angles Theorem; Supplementary Angles

    • B.

      92; Vertical Angles; Alternate Interior Angles

    • C.

      88; Vertical Angles; Alternate Interior Angles

    • D.

      88; Corresponding Angles Theorem; Supplementary Angles

    Correct Answer
    D. 88; Corresponding Angles Theorem; Supplementary Angles
    Explanation
    The correct answer is 88; Corresponding Angles Theorem; Supplementary Angles.

    According to the Corresponding Angles Theorem, when two parallel lines are intersected by a transversal, the corresponding angles are congruent. In this case, m2 and m9 are corresponding angles. Since m2 is given as 92, m9 must also be 92.

    Supplementary angles are two angles that add up to 180 degrees. The sum of m9 and m12 is 180 degrees, so m9 + m12 = 180. Given that m12 is 74, we can solve for m9: m9 + 74 = 180, m9 = 180 - 74, m9 = 106.

    However, this contradicts the information given in the question, which states that m2 = 92. Therefore, the correct answer is 88, not 106.

    Name a segment that is skew to.

    • A.

      Segment VZ

    • B.

      Segment QR

    • C.

      Segment QU

    • D.

      Segment WX

    Correct Answer
    C. Segment QU
    Explanation
    Segment QU is the correct answer because it is the only segment that is skew to another segment in the given options. Skew lines are lines that are not parallel and do not intersect, but are in different planes. In this case, Segment QU and another segment in the options are not parallel and do not intersect, indicating that they are skew to each other.

  • 15. 

    Find x so that l || m. Identify the postulate or theorem you used.

    Correct Answer
    x = 9; Alternate Interior Angles
    Explanation
    The given answer states that x equals 9 and the postulate or theorem used is Alternate Interior Angles. This suggests that the problem involves two parallel lines (l and m) intersected by a transversal. The alternate interior angles are the pair of angles on opposite sides of the transversal and between the two parallel lines. The postulate or theorem states that these angles are congruent. Therefore, if x is equal to 9, it implies that the alternate interior angles are congruent and the lines l and m are parallel.

    Correct Answer
    B. Vertical angles are congruent
    Explanation
    Vertical angles are congruent because they are formed by a pair of intersecting lines and are opposite to each other. This property of vertical angles states that if two angles are vertical angles, then they are congruent. In the given statement, angles CBD and ABF are vertical angles, so they are congruent.

    • E.

      Transitive property of congruence

    Correct Answer
    E. Transitive property of congruence
    Explanation
    The transitive property of congruence states that if angle A is congruent to angle B, and angle B is congruent to angle C, then angle A is congruent to angle C. In this question, statement 1 states that angle CBD is congruent to angle BF, and statement 2 states that angle CBD is congruent to angle ABF. By the transitive property of congruence, we can conclude that angle BF is congruent to angle ABF. Therefore, the correct answer is the transitive property of congruence.

    • E.

      Transitive property of equality

    Correct Answer
    A. Angles that form a linear pair are supplementary
    Explanation
    The given statement states that m∠CBD is equal to m∠BFE. The reason for this is that angles that form a linear pair are supplementary, meaning they add up to 180 degrees. Since m∠CBD + m∠DBF = 180° (as given in the second statement), and m∠CBD is already equal to m∠BFE, it follows that m∠BFE + m∠DBF = 180°. Therefore, option 1 is the correct answer.

    • D.

      Substitution property of equality

    • E.

      Transitive property of equality

    Correct Answer
    D. Substitution property of equality
    Explanation
    The given statement states that m∠CBD is equal to m∠BFE. The reason for this is the Substitution property of equality, which allows us to replace one quantity with another equal quantity. Therefore, we can substitute m∠CBD with m∠BFE in the equation m∠CBD + m∠DBF = 180°, resulting in m∠BFE + m∠DBF = 180°.
