Plantar Fasciitis. Plantar fasciitis is the most common condition that causes heel pain. Plantar fasciitis is due to irritation and inflammation of the tight tissue that forms the arch of the foot. Common symptoms of plantar fasciitis include heel pain with prolonged walking and standing.
Definitions:Complementary angles are two angles with a sum of 90Âº. Supplementary angles are two angles with a sum of 180Âº. Vertical angles are two angles whose sides form two pairs of opposite rays. We can think of these as opposite angles formed by an X. In the triangle shown below, the angles A and B are complementary because they have a sum of 90Âº. This is obvious since angle C is 90Âº and the other two angles must have a sum of 90Âº so that the three angles in the triangle together have a sum of 180Âº.
Two angles are said to be complementary when the sum of the two angles is 90Â°. Two angles are said to be supplementary when the sum of the two angles is 180Â°. If we have two parallel lines and have a third line that crosses them as in the ficture below-the crossing line is called a transversal. When a transversal intersects with two parallel lines eight angles are produced. The eight angles will together form four pairs of corresponding angles.
