  6. BuzzFeed
    Correct! 
    Wrong! 

    This shape has acute angles.

    The shape has obtuse angles, because they are all greater than 90º.

  7. Which of these is an obtuse angle?

    Getty Images
    Correct! 
    Wrong! 

    A

    An obtuse angle is any angle between 90° and 180º.

  8. What are supplementary angles?

    Getty Images
    Correct! 
    Wrong! 

    Supplementary angles add up to 180º.

  9. BuzzFeed
    Correct! 
    Wrong! 

    70º

    These two angles are complementary, meaning their sum equals 90º. 90 minus 20 is 70, so angle X = 70º.

  10. BuzzFeed
    Correct! 
    Wrong! 

    55º

    These two angles are supplementary angles, meaning they add up to 180º. 180 minus 125 is 55, so Z = 55º.

    Correct! 
    Wrong! 

    True

    A rectangle has four right angles and the opposite sides are equal — all of which is true for squares. But every side of a square must be equilateral, which is not true of rectangles.
