Since a square is a parallelogram, a rectangle, and a rhombus, our symmetry observations for a square will be the same as those we have already seen. A trapezoid has no reflectional symmetry and no rotational symmetry. We cannot make observations.
1 Return beef and accumulated juices to pan. Stir-fry for a few minutes. Add water, tomato sauce, liver spread and bay leaf; stir to combine. Bring to a boil then simmer, about an hour or until meat tender.  Add potatoes, carrots and green olives; simmer for another 6 to 8 minutes.
SautÃ© the onion and green pepper in the olive oil until tender. Add the garlic, and sautÃ© another minute or two. Add the tomato paste, black beans, oregano, cumin, bay leaf, and vinegar. Cook for about five minutes, stirring gently. Add the chicken stock and the rinsed rice. Bring to a boil, reduce heat to low, cover and cook for about 20-30 minutes -- until the rice is fully cooked.
