Lines and AnglesQuiz - Solve & Score

A few sample questions with instant answers and solutions - the full set is in the app.

  1. Q1. If two parallel lines are cut by a transversal, then which pair of angles is equal?

    • A.Corresponding angles
    • B.Co-interior angles
    • C.Linear pair
    • D.Adjacent supplementary

    Answer: A. Corresponding angles

    Which principle settles this? Corresponding angles are equal when the two lines are parallel. (Alternate interior angles are also equal, but the option here is corresponding.). Pick: A) Corresponding angles.

  2. Q2. A carpenter cuts a corner brace so that its two parts together form the right angle of a window frame. If one part measures 18 degrees, what is the measure of the other part?

    • A.162 degrees
    • B.108 degrees
    • C.72 degrees
    • D.18 degrees

    Answer: C. 72 degrees

    The two angles complete a right angle, so they are complementary and sum to 90 degrees. Other = 90 - 18 = 72 degrees.

  3. Q3. On a folding table leg, the brace makes a right angle with the floor split into two pieces by a rivet. One piece is 22 degrees; how large is the remaining piece?

    • A.68 degrees
    • B.22 degrees
    • C.112 degrees
    • D.158 degrees

    Answer: A. 68 degrees

    The two angles complete a right angle, so they are complementary and sum to 90 degrees. Other = 90 - 22 = 68 degrees.
