What is the size of an exterior angle of octagon?
360/8 = 45 degrees
What is the size of each angle in a regular 25 sided shape?
Exterior angle = 14.4 degrees Interior angle = 165.6 degrees
What is the size of an exterior angle of nonagon?
360/9 ie 40 degrees
What is the size of each interior angle at each vertex of a regular pentagon?
Exterior angle = 360/Number of sides = 360/5 = 72 degrees. Interior angle = 180 - Exterior angle = 180 - 72 = 108 degrees.
How do you work out exterior angle for a triangle?
It is: 180-interior angle = exterior angle
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.
What is the size of one exterior angle in a regular hexagon?
Each exterior angle is 360/6 = 60 degrees
What is the size of each exterior angle of a regular pentagon?
Interior angles are 108o. 360 - 108 = 252o for each exterior angle * * * * * Each exterior angle is 360/5 = 72 degrees, NOT 252. The 108 for the interior angle is correct, but to get from interior to exterior you subtract from 180, not 360!
A regular polygon an exterior angle of 30 What is the size of the interior angle?
Exterior angles are supplementary with interior angles, so 180-30=150
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 is the size of an exterior angle of octagon?
360/8 = 45 degrees
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 is an exterior angle of a triangle and how does the measure of an exterior angle relate to the interior angles?
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
What is the size of one interior angle in a regular octagon?
135 degrees and its exterior angle is 45 degrees
What is the size of each interior angle if each exterior angle is 24?
It is: 180-24 = 156 degrees
What is the size of each angle in a regular 25 sided shape?
Exterior angle = 14.4 degrees Interior angle = 165.6 degrees
What is the size of an exterior angle of nonagon?
360/9 ie 40 degrees
