The interior angle of a polygon is the angle formed by two adjacent sides of a polygon where the angle lies inside the area formed by the polygon. The exterior angle is that formed by one of these sides and the line formed by extending the other side. Consequently, External angle = 180 deg - Internal angle. Because they form supplementary angles, it does not matter which of the two sides you extend.

How do you work out exterior angle for a triangle?
It is: 180-interior angle = exterior angle
What is the Formula to find out exterior angle of a hexagon?
180 - interior angle = exterior angle
What is the exterior and interior angle of a heptagon?
the interior angle is about 128.571428 the exterior angle is about 51.4285
What is the exterior angle the interior angle and the angle at the center of a regular polygon with 15 sides?
Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.
What is the exterior angle of a pollygon?
An exterior angle of a polygon is the supplement of the corresponding interior angle. The exterior angle is the angle between an extended sides of the polygon and the next side of the polygon.
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 an exterior angle of a triangle?
It is: 180-interior angle = exterior angle
What is a Exterior angle of a triangle?
It is: 180-interior angle = exterior angle
How do you find exterior angle?
the hypotenuse is the exterior angle
Can the exterior angle of triangle be straight angle?
When any side of triangle is extended outwards then exterior angle is formed. Sum of this exterior angle and adjacent interior angle = 180o. If exterior angle = 180o(straight angle) then interior adjacent angle is 0o which is not possible. So exterior angle can't be straight angle.
How is an exterior angle of a polygon formed?
180 - interior angle = exterior angle
What is an exterior angle for a triangle?
180 minus interior angle = exterior angle
What is the exterior angle for a octagon?
180 minus interior angle = exterior angle
How do you work out exterior angle for a triangle?
It is: 180-interior angle = exterior angle
What is the measure of a exterior of an angle of a tringle?
180-interior angle = exterior angle
How do you find a exterior angle?
180-interior angle = exterior angle If it's a regular polygon then: 360/number of sides = exterior angle
What is the measure of an exterior angle adjacent to the vertex angle?
It is: 180-vertex angle = exterior angle
