  1. 1. (d) 360° — A quadrilateral's angles sum to 360°.
  2. 2. (b) equal and parallel — Opposite sides are equal and parallel.
  3. 3. (c) bisect each other — Parallelogram diagonals bisect each other.
  4. 4. (d) rhombus — Equal sides make it a rhombus.
  5. 5. 360°.
  6. 6. All four sides are equal (its diagonals are also perpendicular).
  7. 7. In parallelogram ABCD, AB ∥ DC and AD ∥ BC. Using the alternate-angle property with diagonal AC, triangles ABC and CDA are congruent (ASA). Hence ∠B = ∠D, and similarly ∠A = ∠C — opposite angles are equal.
