What is the relationship between the measure of a central angle of a polygon and the measures of an interior and an exterior angle of the polygon?
The interior angle and central angle are supplementary, that is they always add up to 180 degrees, while the exterior angle and the central angle will always be the same.
What is The measure of an angle is 20 and deg. What is the measure of its supplement?
Its supplementary angle is 160 degrees because supplementary angles add up to 180 degrees
What is the measure of the angle that supplementary to 30 degree angle?
150 degrees
What is the measure in degrees of an angle that is supplementary to a 74 degree angle?
74
Which has a greater measure an angle complementary to an angle measuring 58 degrees or an angle supplementary to an angle measuring 125 degrees?
It is the supplementary angle of 125 degrees which is 55 degrees
How do you find the exterior angle from a interior angle?
The interior angle and the exterior angle are supplementary. That's why you learned about supplementary angles ... or at least they were presented in class ... before polygons.
Is the measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle?
No. The interior angle and exterior angle at the same vertex are supplementary. Each of them is (180 degrees minus the other). In rectangles (including squares), the interior and exterior angles at each vertex are both right angles.
What is the sum of the measure of a supplementary angle?
A supplementary angle can have any value - depending on the first angle.
What is the relationship between the measure of a central angle of a polygon and the measures of an interior and an exterior angle of the polygon?
The interior angle and central angle are supplementary, that is they always add up to 180 degrees, while the exterior angle and the central angle will always be the same.
A supplementary angle to a 76 angle has a measure of?
104
An interior angle of a polygon and its adjacent exterior angle are complementary?
No, they are supplementary, not complementary.
How do you find the measure of an interior angle with 16 sides?
You cannot. An interior angle of a 16-sided polygon can have any value. However, IF the polygon is regular, then each of its exterior angles is 360/16 = 22.5 degrees. The interior angle, being a supplementary angle to the exterior angle, will be 180-22.5 = 157.5 degrees.
What supplementary angle to a 79 degree angle has a measure of?
101
What is the relationship between the interior and exterior angles in polygons?
An interior angle and the corresponding exterior angle add up to a straight angle. that is, they are supplementary.
What is the measure of a supplementary angle to a 97 degree angle?
83 degree angle
What is The measure of an angle is 20 and deg. What is the measure of its supplement?
Its supplementary angle is 160 degrees because supplementary angles add up to 180 degrees
The measure of an interior angle of a regular polygon is 150 degrees Find the number of sides?
AnswerIt is Dodecagon.To find this, you have to first find the exterior angle of the polygon. Since the exterior angle of a polygon is always supplementary to the interior angle, you subtract the measure of the interior angle from 180. 180-150=30. Now You divide 360 by the measure of the exterior angle to get the number of sides of the polygon. 360/30=12. A 12-sided polygon is called a dodecagon
