  1. The diagonals of which quadrilateral are always equal and bisect each other?

    Answer: Rectangle

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

  2. A polygon with all sides and all angles equal is called:

    Answer: Regular

    A regular polygon is both equilateral and equiangular.

  3. The diagonals of a rhombus intersect at what angle?

    Answer: 90°

    A rhombus's diagonals are perpendicular, meeting at 90°.

  4. If a regular polygon has interior angles of 150°, how many sides does it have?

    Answer: 12

    An exterior angle of 30° gives 360°/30° = 12 sides.

  5. Which statement about a kite is true?

    Answer: It has two pairs of adjacent equal sides

    A kite has two distinct pairs of adjacent congruent sides.

  6. The area of a trapezoid is found using which formula?

    Answer: ½(b₁+b₂) × height

    A trapezoid's area is half the sum of the parallel bases times the height.

  7. A concave polygon must have at least one interior angle that is:

    Answer: Greater than 180°

    Concave polygons contain a reflex angle greater than 180°.
