The condition is thought to be caused by a combination of side effects of the drug (clenching and grinding of teeth, dry mouth) and lifestyle factors (infrequent oral hygiene, frequent consumption of sugary drinks), which may be present in long term users.
An Interior Angle is an angle inside a shape. Note: When we add up the Interior Angle and Exterior Angle we get a straight line, 180Â°. (See Supplementary Angles).
The consecutive interior angles theorem states that when the two lines are parallel, then the consecutive interior angles are supplementary to each other. Supplementary means that the two angles add up to 180 degrees. The theorem tells me that angles 3 and 5 will add up to 180 degrees. Angles 4 and 6 will also add up to 180 degrees because they make another pair of consecutive interior angles.
