  • 2. 

    Which of the following is always congruent even if lines are not parallel?

    • Consecutive interior angles

    • Vertical angles

    • Alternate exterior angles

    • Corresponding angles

    Correct Answer
    A. Vertical angles
    Explanation
    Vertical angles are always congruent, regardless of whether the lines are parallel or not. Vertical angles are formed by two intersecting lines and are opposite to each other. They have equal measures and are congruent because they are formed by the same pair of intersecting lines. This property holds true for any pair of vertical angles, regardless of the orientation of the lines.

    Which of the following are methods to prove two lines are parallel when cut by a transversal?

    • Alternate exterior angles are congruent.

    • Consecutive interior angles are congruent.

    • Corresponding angles are supplementary.

    • Alternate interior angles are congruent.

    Correct Answer
    A. Alternate interior angles are congruent.
    Explanation
    The method to prove two lines are parallel when cut by a transversal is by showing that the alternate interior angles are congruent. This means that the angles on the inside of the two lines, but on opposite sides of the transversal, are equal in measure. If the alternate interior angles are congruent, it indicates that the lines are parallel.

    What is the relationship of the slopes on perpendicular lines?

    • Opposite

    • Opposite reciprocals

    • Reciprocals

    • Equal

    Correct Answer
    A. Opposite reciprocals
    Explanation
    Perpendicular lines have slopes that are opposite reciprocals of each other. This means that if one line has a slope of m, the perpendicular line will have a slope of -1/m.

    Rate this question:

  • 5. 

    Which of the following angle pairs are congruent because parallel lines are cut by a transversal?

    • Corresponding

    • Alternate interior

    • Alternate exterior

    Correct Answer(s)
    A. Corresponding
    A. Alternate interior
    A. Alternate exterior
    Explanation
    When parallel lines are cut by a transversal, corresponding angles, alternate interior angles, and alternate exterior angles are congruent. Corresponding angles are formed when a transversal intersects two parallel lines and are located in the same relative position on each line. Alternate interior angles are located on opposite sides of the transversal and inside the two parallel lines. Alternate exterior angles are located on opposite sides of the transversal and outside the two parallel lines. Therefore, all three angle pairs mentioned in the answer (corresponding, alternate interior, and alternate exterior) are congruent when parallel lines are cut by a transversal.
