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.

(Luke 1997; 2001). Although the soft tissue of the pineal does not accumulate fluoride to the same extent as the calcified part, it does contain higher levels of fluoride than found than in other types of soft tissue in the body â with concentrations (~300 ppm F) that are known in other contexts to inhibit enzymes.
