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...
Explain to the student that a line of symmetry is an imaginary line that divides a figure into two congruent parts, each of which is the mirror image of the other. Provide the student with a mirror. Have the student use the mirror to determine if a line drawn is actually a line of symmetry. Provide additional practice through a symmetry sort. Provide the student with two-dimensional figures (some with lines of symmetry and some with lines drawn that are not lines of symmetry).
