  1. What is the sum of the interior angles of a hexagon?

    Answer: 720°

    Using (n-2)×180° with n=6 gives 4×180° = 720°.

  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 measure of each interior angle of a regular pentagon is:

    Answer: 108°

    The interior angle sum 540° divided by 5 sides equals 108°.

  4. In a parallelogram, consecutive angles are always:

    Answer: Supplementary

    Consecutive angles in a parallelogram add to 180°, making them supplementary.

  5. How many diagonals does a regular octagon have?

    Answer: 20

    Using n(n-3)/2 with n=8 gives 8×5/2 = 20 diagonals.

  6. A quadrilateral with four equal sides but no right angles is a:

    Answer: Rhombus

    A rhombus has four congruent sides without requiring right angles.

  7. What is the measure of each exterior angle of a regular hexagon?

    Answer: 60°

    Exterior angles of any polygon sum to 360°, so 360°/6 = 60°.
