To show triangles are congruence they are four ways. 1  If all three sides of triangle are same then they are congruent. (SSS) 2  If two sides of triangle and the angle connecting them are the same ( SAS) 3  Two angles and a corresponding side (ASA or AAS) 4  Right angled triangles only the hypotenuse and one side are the equal (RHS)
The severity of symptoms is related to the severity of the fever. Fever and systemic symptoms typically last 3 days, occasionally up to 4-8 days, and gradually diminish; however, cough and malaise may persist for more than 2 weeks. Second fever spikes are rare. The physical findings are summarised in table 3. Full recovery may take 1-2 weeks, or longer, especially in the elderly. Table 3. Physical findings of uncomplicated influenza. Fever: rapidly peaking at 38-40Â°C (up to 41Â°C, especially in children), typically lasting 3 days (up to 4-8 days), gradually diminishing; second fever spikes are rare.
An otherwise healthy person who gets the flu will usually improve over two to five days. In some people that tired feeling may last for one week or more and very rarely the symptoms can last for several weeks (post influenza asthenia). A major concern when you get the flu is that complications can arise. This is not strictly a relapse, but the development of another illness. The risk is highest for those with diabetes; heart, lung, or kidney disease; and other chronic diseases that lower the body's resistance to infection. Persons over age 65 are also at greater risk of developing complications from the flu. A very serious complication associated with the flu is pneumonia. Shortness of breath, sharp chest pain on deep breathing, or fever lasting beyond five days are symptoms that may indicate pneumonia.
