Myocarditis is a disease marked by the inflammation of the heart muscle known as the myocardium â the muscular layer of the heart wall. This muscle is responsible for contracting and relaxing to pump blood in and out of the heart and to the rest of the body. When this muscle becomes inflamed, its ability to pump blood becomes less effective.
Line Symmetry. shape has line symmetry when one half. of it is the mirror image of the other half. Symmetry exists all around us and many people see it as being a thing of beauty. Symmetry is...
Reflection and rotational symmetry together A shape can have no lines of symmetry, but its order of symmetry must be at least one. For regular polygons, the number of lines of symmetry is equal to the order of rotational symmetry, and both are equal to the number of sides.For example, a pentagon has five sides, five lines of symmetry and an order of rotational symmetry of five.The order of rotational symmetry of a shape is always equal to or greater than the number of lines of symmetry it has. Consider the shapes below.here is a number called the order of rotational symmetry. This is how many times the shape looks the same as it is rotated through 360Â°. Shown below are the stages of rotating an equilateral triangle through 360Â°. Each triangle is rotated 30Â° clockwise from the one to its left.
