What is an angle that is formed on the outside of a polygon by extending one side?
The size of the angle would depend on the shape and number of sides the polygon has. It is called the exterior angle.
What size are exterior angles on a regular polygon have if each interior angle is 172.5 and how many sides does it have?
Exterior angles are 7.5 There are 48 sides.
What is the size of an interior angle of a 20 sided regular polygon?
exterior angle = 360° ÷ 20 sides = 18° interior angle = 180° - exterior angle = 180° - 18° = 162°
What shape has 4 congruent sides with no right angle?
Rhombus. Because a rhombus has congruent (egual in shape and size) sides, but has no right angles.
How do you find how many sides of a polygon has with the measure of an exterior angle?
The sum total of all exterior angles of any polygon is 360 degrees. So if you're given thevalue of one exterior angle AND THE POLYGON IS REGULAR(all exterior angles are thesame size), all you have to do is divide the size of one angle into 360, and the quotientis the number of sides.
What effects the size of an angle?
The length of it's sides
Is it true that as the no. of sides of polygon increases each interior angle and exterior angle also increase?
No because each interior angle increases in size whereas each exterior angle decreases in size.
If a quadrilateral has a right angle is it a triangle?
No because a quadrilateral has 4 sides whereas a triangle has 3 sides.
What is the size of an interior angle of a regular polygon with 8 sides?
135 dregrees
What is the size of each interior angle of a regular polygon with 13 sides?
Each interior angle is: 1520 18' 27.69''
What is the size of each interior angle of a regular 14 sides polygon?
Each interior angle is: 1540 17' 8.57''
What is the size of each interior angle of a regular 23 sides polygon?
Each interior angle: 1640 20' 52.17''
How do you find out the size of a regular polygon?
Divide the number of sides into 360 which will give you the exterior angle and subtract this angle from 180 which will give you the interior angle.
A regular polygon has 12 sides what is the size of each interior angle?
150 degrees
One angle of polynomial is 144 degree.find no of sides of polynomial?
The sum of the exterior angles of a polygon is 360o. Dividing 360o by the size of the exterior angle gives the number of sides. If the interior angle is 144o, the exterior angle is 180o - 144o = 36o. Number of sides = 360o / 36o = 10 (a decagon).
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 size is a right angle?
There can be as many sizes as you want but the right angle always has an 90 degree angle in it but the length of the sides can be varied (they can be as long as or as short as you want). :)
