How do you work out exterior angle for a triangle?
It is: 180-interior angle = exterior angle
How do you work out the number of sides in a regular polygon that has an exterior angle?
With a regular polygon: 360/exterior angle = number of sides
How do you work out the interior angle if known the exteria angle?
To find the interior angle of a polygon when you know the exterior angle, you can use the relationship that the interior and exterior angles are supplementary. This means they add up to 180 degrees. Therefore, you can calculate the interior angle by subtracting the exterior angle from 180 degrees: Interior Angle = 180° - Exterior Angle.
How do you work out the exterior angle of a triangle?
Interior and adjacent exterior angles form a straight line so exterior angle = 180 - interior angle. If you are satisfied with this reply please consider awarding a Recommended Point to the responder.
What is an exterior angle of a nonagon?
The sum of the exterior angles in any polygon is 360 degrees. A nonagon has 9 sides, so to work out a single exterior angle, we divide 360 by 9, which is 40.
How do you work out exterior angle for a triangle?
It is: 180-interior angle = exterior angle
How do you work out exterior angle of an decagon?
You cannot. An exterior angle of a decagon can have any value.
How do you work out the number of sides in a regular polygon that has an exterior angle?

How do you work out the interior and exterior angles of a regular polygon?
If the polygon has n sides (or vertices) each exterior angle is 360/n. Each interior angle = 180 - exterior angle = 180 - 360/n
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

How do you find exterior angle?
the hypotenuse is the exterior angle
Work out the exterior and interior angles of a regular polygon with 8 sides?
Each exterior angle 45 degrees Each interior angle 135 degrees
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.
