Questions and Answers
  • 1. 

    Angles a and b are:

    • A.

      Alternate

    • B.

      Co-interior

    • C.

      Vertically-opposite

    • D.

      Corresponding

    • E.

      Exterior

    Correct Answer
    C. Vertically-opposite
    Explanation
    Vertically-opposite angles are formed when two lines intersect. In this case, angles a and b are formed by the intersection of two lines. Vertically-opposite angles are always equal to each other, meaning that angle a is equal to angle b. This is why the answer is vertically-opposite.

    Angles a and c are:

    • A.

      Alternate

    • B.

      Co-interior

    • C.

      Vertically-opposite

    • D.

      Corresponding

    • E.

      Exterior

    Correct Answer
    D. Corresponding
    Explanation
    Angles a and c are corresponding angles. Corresponding angles are formed when a transversal intersects two parallel lines. In this case, the angles a and c are located in the same position on the two parallel lines, one on each line. Corresponding angles have equal measures, so angle a and angle c are equal.

  • 3. 

    Angles b and c are:

    • A.

      Alternate

    • B.

      Co-interior

    • C.

      Vertically-opposite

    • D.

      Corresponding

    • E.

      Exterior

    Correct Answer
    B. Co-interior
    Explanation
    Angles b and c are co-interior angles because they are located on the same side of the transversal line and on the inside of the two parallel lines. Co-interior angles are supplementary, which means that their sum is equal to 180 degrees. In this case, angles b and c add up to 180 degrees, indicating that they are co-interior angles.

  • 4. 

    Angles b and g are:

    • A.

      Alternate

    • B.

      Co-interior

    • C.

      Vertically-opposite

    • D.

      Corresponding

    • E.

      Exterior

    Correct Answer
    A. Alternate
    Explanation
    Angles b and g are alternate angles. Alternate angles are formed when a transversal intersects two parallel lines. In this case, the angles b and g are on opposite sides of the transversal and on different parallel lines. Alternate angles are congruent, meaning they have the same measure.

    Rate this question:

  • 5. 

    How many degrees is angle a?

    Correct Answer
    63, sixty three, 63 degrees, 63 degree, sixty-three degree
    Explanation
    The given answer "63, sixty three, sixtythree" indicates that angle a measures 63 degrees. The angles are vertical, which means they are equal to each other. Thus, if one angle is 63 degrees, then so is the other angle.

    Rate this question:

  • 6. 

    How many degrees is angle a?

    Correct Answer
    70, seventy
    Explanation
    Angle “a” and 110 degrees are supplementary angles. They add up to equal 180. Thus, to determine what angle a is we will subtract 110 from 180 which will give us 70 for angle “a”. 

    Rate this question:

  • 7. 

    How many degrees is angle c?

    Correct Answer
    110, one hundred and ten, one hundred ten
    Explanation
    70 degrees and angle “c” are co-interior angles. They add up to equal 180. Thus, to determine what angle “c” is we will subtract 70 from 180, which gives us 110.

    Rate this question:

  • 8. 

    what is the size of angle g?

    • A.

      70°

    • B.

      110°

    Correct Answer
    A. 70°
    Explanation
    The size of angle g is 70°. Both angles are alternate, which means they are equal to each other. Thus, angle “g” is also 70 degrees.

    Rate this question:

  • 9. 

    How many degrees is angle g?

    • A.

      125

    • B.

      180

    • C.

      135

    • D.

      90

    • E.

      55

    Correct Answer
    E. 55
    Explanation
    The correct answer is 55 because angle g and 55 degrees are corresponding angles, which means they are equal. 

    Rate this question:

  • 10. 

    What is the size of angle d?

    • A.

      55°

    • B.

      90°

    • C.

      125°

    • D.

      180°

    • E.

      25°

    Correct Answer
    A. 55°
    Explanation
    The size of angle d is 55°. Angle b and 55 degrees are vertical angles, which means they are equal. Thus, angle b is 55. However, angle b and angle d are corresponding angles. Corresponding angles are equal to each other. Thus, angle d is 55. 

    Rate this question:

  • 11. 

    How many degrees is angle f?

    Correct Answer
    140, one hundred and forty, one hundred forty
    Explanation
    Angle f and 40 degrees are co-interior angles. Co-interior angles are supplementary which mean they add up to equal 180. Thus, we will subtract 40 from 180 to determine that angle f is 140 degrees. 

    Rate this question:

  • 12. 

    How many degrees is angle b?

    Correct Answer
    40, forty
    Explanation
     Angle “b” and 40 degrees are alternate angles. Alternate angles are equal to each other. Thus, angle b is also 40 degrees. 

    Rate this question:

  • 13. 

    How many degrees is angle a?

    • A.

      180°

    • B.

      40°

    • C.

      200°

    • D.

      140°

    • E.

      50°

    Correct Answer
    D. 140°
    Explanation
    Angle f and 40 degrees are co-interior angles. Co-interior angles are supplementary, which means they add up to equal 180. Thus, we will subtract 40 from 180 to determine that angle f is 140 degrees. However, angle “a” and angle “f” are vertical angles, which means they are equal. Thus, if angle f is 140, then angle “a” is also 140.

    Rate this question:

  • 14. 

    How many degrees is angle a?

    • A.

      60°

    • B.

      120°

    • C.

      180°

    • D.

      160°

    • E.

      80°

    Correct Answer
    B. 120°
    Explanation
    Angle “a” and 120 degrees are vertical angles, which means they are equal. Thus, angle “a” is also 120.

    Rate this question:

  • 15. 

    How many degrees is angle c?

    Correct Answer
    120, one hundred and twenty, one hundred twenty
    Explanation
    Angle “c” and 120 degrees are alternate angles, which means they are equal. Thus, angle “c” is also 120.

    Rate this question:

  • 16. 

    How many degrees is angle d?

    Correct Answer
    60, sixty
    Explanation
    Angle “c” and 120 degrees are alternate angles, which means they are equal. Thus, angle “c” is also 120. However, angle “c” and angle “d” are supplementary angles that add up to equal 180. To determine angle “d” you will subtract 120 from 180, which will be 60 degrees.
