I don't think this forum is a dental school, but just for your amusement, line angles generally do not matter unless you are placing amalgams, gold foils or inlays, none of which are very common nowadays with possible exception of inlay in some so-called high end dental clinics.
What else can I help you with?
When the number of sides of a regular polygon increases what happens to the size of each exterior angle of the polygon?
Each external angle is equal to 360/n degrees where n is the number of sides (or angles) of the polygon. So the external angle is inversely proportional to the number of sides.
What is an external angle of a right angle?
90 degrees
What is the measure of each external angle of a square?
Each external angle of a square is 270o (360o - 90o).
Are the internal angle and external angle of a polygon supplementary?
yes.
What are external angles?
An external angle is the angle between the outside of one side and the extension of the adjacent line. They all add to 360o.
What is the external angle of a triangle?
360 degrees take away the internal angle
What is the external angle if the internal angle is 135 degree?
180-135 = 45 degrees
Why is 135degrees the measurement of an angle of an octagon?
The external angle of a polygon is equal to 360/n, n representing the number of sides in the polygon. Since an octagon has eight sides, the external angle of a regular octagon is 360/8 = 45 degrees. Since a straight angle in a polygon would be equal to 180 degrees, you subtract the measure of the external angle from this, to make an internal angle of 180 - 45 = 135 degrees.
How many sides does a polygon have when its internal angles are 150 degrees?
Internal angle = 150° → external angle = 360° - 150° = 30° number of sides = 360 ° ÷ external angle = 360° ÷ 30° = 12 It has 12 sides.
What is the external angle of an octagon?
45 degrees(360/8)
What is the internal angle of undecagon.?
we have eleven sides in external and internalangle..
Which of these two regular polygons has the larger interior angle pentagon or square?
Each vertex angle of a polygon is composed of an external angle and an interior angle. These two angles are supplementary (total 180°). As the number of sides of a regular polygon increases then the external angle decreases and conversely, the interior angle increases. The interior angle of a regular pentagon (108°) is larger than the interior angle of a square (90°).
