Liver of frog OR liver of Human do the same function. it produces bile and cleans waste products from the body. It filters the food of the frog by separating the nutrients and the not needed things of the frog's food. The liver aids in breaking down foods.
Shapes with Parallel Sides. There are several shapes that have parallel sides as a distinguishing feature. The most common are the parallelogram, the rectangle, the square, and the trapezoid. These are the ones that you will most often hear about as having parallel sides. The trapezoid has one pair of parallel sides. The parallelogram, rectangle, and square all have two pairs of parallel sides. Other less common shapes with parallel sides include any of the '-gons' with an even number of sides, such as a hexagon, octagon, decagon, etc.
A parallelogram is a four-sided shape with opposite sides that are parallel. Because of the parallel lines, the opposites sides are equal in length. There are some unique properties of the angles inside parallelograms. First, the opposite angles are equal. Also, the adjacent angles are supplementary, which means they add up to 180 degrees. The perimeter of the parallelogram below, where the sides are 4, 4, 5 and 5, is 18. Example of a parallelogram When we have a specific type of quadrilateral like the one below, we can determine its area.
