  5. A shape has 2 pairs of parallel sides and no right angles. What could it be?

    1. Rectangle
    2. Trapezoid
    3. Triangle
    4. Parallelogram
    Show answer

    Answer: Parallelogram

    A parallelogram has 2 pairs of parallel sides but does not require right angles.

  6. A trapezoid has 2 pairs of parallel sides.

    Show answer

    Answer: False

    A trapezoid has exactly 1 pair of parallel sides, not 2.

  7. An angle that forms a perfect square corner is called a ___ angle.

    Show answer
