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.
Cooking Procedures 1  : In a large pan, heat oil. Fry the potatoes and carrots until color turns light brown. Remove and set aside. 2  Add beef to the pan; stir-fry for a few minutes until lightly brown. Remove and set aside.  In the same pan, sautÃ© the garlic and onions until translucent. Add chili flakes.
Heat a large cast-iron skillet over medium-high heat. Add tomatillos; cook, turning a few times, until blistered in spots and beginning to soften, 10 to 12 minutes. Transfer to a bowl, cover with plastic wrap, and let steam 15 minutes. Add garlic to skillet and cook over medium heat, turning a few times, until blistered and fragrant, 1 to 2 minutes. Transfer to a blender. Add chiles to skillet and cook, turning frequently, just until toasted and soft, 30 to 60 seconds. Transfer to blender with tomatillos and accumulated juices, salt, and 2 tablespoons water. Blend to consistency of a thin salsa, about 10 seconds.
