In elementary geometry the word congruent is often used as follows. The word equal is often used in place of congruent for these objects. 1  Two line segments are congruent if they have the same length. 2  Two angles are congruent if they have the same measure.3  Two circles are congruent if they have the same diameter.ore formally, two sets of points are called congruent if, and only if, one can be transformed into the other by an isometry, i.e., a combination of rigid motions, namely a translation, a rotation, and a reflection.
Calcium deposits in soft tissue (Soft Tissue Calcification, STC) are well known phenomena in the medical world. Unlike healthy calcification that is responsible for bones and teeth, STC is associated with numerous diseases and conditions that pose serious health concerns.alcium deposits in soft tissue (Soft Tissue Calcification, STC) are well known phenomena in the medical world.

Calcification can be the bodyâs protective response to injury, as well as part of a natural inflammatory reaction to infection, trauma, or autoimmune disorders. Also, tumors (cancerous or noncancerous) can result in calcification within the tumor tissue. Calcification becomes a problem when its location, shape or size interferes with the organ function, such as calcifications that harden and block blood vessels in the heart, brain and kidney. For example, with advancing age both the aortic and mitral valves can thicken and develop calcification deposits. This can lead to decreased efficiency in the heartâs pumping ability. Calcifications that are apparent on mammograms may signal the presence of breast cancer, or they may occur with benign breast disease.
