2. Parallelogram RectangleRhombus Square -Diagonals ≅ -Corner angles 90° -Center angles 90° -Corner angles bisected -All sides ≅ -Opp. sides ≅ -Opp. sides parallel -Consecutive angles add to 180° -Diagonals bisected -Opp. angles ≅

3. Always, Sometimes, or Never If a shape is a square, then it is a rhombus. If a shape is a rectangle, then it is a square. If a shape is a parallelogram, then it is a rhombus. If a shape is a rhombus, then it is a square. If a shape is a square, then it is a parallelogram. If a shape is a rectangle, then it is a rhombus Always Sometimes Always Sometimes (a square)
