ROENTGENOLOGY LAB BISECTING ANGLE TECHNIQUE & PARALLELIGN TECHNIQUE

Bisecting- angle technique

used often in the first half of the twentieth century but has been largely replaced by the paralleling technique.

-Large rigid sensors

-The anatomy of the patient

This states that two triangles are equal when they share one complete side and have two equal angles.

-lingual surface of teeth

-resting in the paralte or floor of mouth
