Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments.Note they are laying at different angles.If you drag any of the four endpoints, the other segment will change length to remain congruent with the one you are changing. For line segments, 'congruent' is similar to saying 'equals'.n the figure above, there are two congruent line segments. Note they are laying at different angles. If you drag any of the four endpoints, the other segment will change length to remain congruent with the one you are changing.
Sonogram vs. Ultrasound. A sonogram is the image generated during ultrasonography, which is a diagnostic imaging technique that uses ultrasound to visualize anything inside the body. Ultrasound is sound with a frequency above the range audible to humans, about 20 kHz. In common parlance, both words are used to refer to the ultrasonography procedure.
Diagnostic medical sonography is a type of medical imaging that uses high-frequency sound waves, also known as ultrasound, to produce images of organs, tissues and blood flow. A common example of sonography is the technology that allows expectant parents to see the first images of their unborn child. Sonography images are ordered by a doctor and obtained by a sonography technician who uses a device called a transducer.
