How is an exterior angle of a polygon formed?
180 - interior angle = exterior angle
What is the measureof the exterior angle to a straight angle?
a circle = 360 degrees , so 360 - straight angle = exterior angle
Exterior angle property of a triangle?
measure of exterior angle of triangle is equal to sum of interior angles. for eg. In triangle ABC, angle C is exterior angle angle A and angle B are interior angles so, C=A+B
What is the measure of one exterior angle of a decagon?
Each interior angle of a decagon is 144 degrees.An exterior angle is 180 - measure of interior angle.There exterior angle of decagon is 180-144which is equal to-36
An exterior angle of a triangle is 180 degrees.?
No.Take a look at this picture...http://www.onemathematicalcat.org/Math/Geometry_obj/graphics/summing_exterior_angles.pngThe exterior angle + the interior angle = 180 degrees180 - the interior angle = the exterior angle
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.
What is the exterior angle for a octagon?
180 minus interior angle = exterior angle
What is the measure of a exterior of an angle of a tringle?
180-interior angle = exterior angle
What is an exterior angle for a triangle?
180 minus interior angle = exterior angle
How is an exterior angle of a polygon formed?
180 - interior angle = exterior angle
How do you work out exterior angle for a triangle?
It is: 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
