  1. A parallelogram has a base of 8 cm and a height of 5 cm. What is its area?

    Answer: 40 cm²

    The area of a parallelogram equals base times height, so 8 × 5 = 40 cm².

  2. Which quadrilateral has exactly one pair of parallel sides?

    Answer: Trapezoid

    A trapezoid is defined by having exactly one pair of parallel sides.

  3. The diagonals of which quadrilateral are always equal in length AND bisect each other?

    Answer: Rectangle

    A rectangle's diagonals are congruent and bisect each other.

  4. Three angles of a quadrilateral measure 90°, 85°, and 95°. What is the fourth angle?

    Answer: 90°

    Angles of a quadrilateral sum to 360°, so 360 − (90+85+95) = 90°.

  5. What is the perimeter of a rhombus with a side length of 7 inches?

    Answer: 28 in

    A rhombus has four equal sides, so perimeter = 4 × 7 = 28 inches.

  6. Which statement is TRUE for every square?

    Answer: It is also a rectangle and a rhombus

    A square satisfies the definitions of both a rectangle and a rhombus.

  7. A trapezoid has parallel sides of 6 cm and 10 cm and a height of 4 cm. What is its area?

    Answer: 32 cm²

    Area = ½(b₁+b₂)h = ½(6+10)(4) = 32 cm².
