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 is a process in which calcium builds up in body tissue, causing the tissue to harden. This can be a normal or abnormal process. Ninety-nine percent of calcium entering the body is deposited in bones and teeth. The remaining calcium dissolves in the blood. When a disorder affects the balance between calcium and certain chemicals in the body, calcium can be deposited in other parts of the body, such as the arteries, kidneys, lungs, and brain. Calcium deposits can cause problems with how these blood vessels and organs work. Calcifications can usually be seen on x-rays.
