What is an exterior angle of a triangle?
It is: 180-interior angle = exterior angle
What is the interior of a circle called?
the interior of a circle is called a cabret
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!
What is the relationship between the interior and exterior angles in polygons?
An interior angle and the corresponding exterior angle add up to a straight angle. that is, they are supplementary.
How many sides does an equiangular polygon have if the measure of an angle of the polygon exceeds four times the measure of one of it's exterior angles by 30?
Interior angle + Exterior angle = 180 So Interior angle = 180 - Exterior angle Interior angle = 4*Exterior angle + 30 Substitute for Interior angle: 180 - Exterior angle = 4*Exterior angle + 30 Collect like terms: 150 = 5*Exterior angle Divide by 5: Exterior angle = 30 deg Therefore number of sides = 360/30 = 12
If the sum of the measures of the interior angles of a polygon equals the sum of the measures of its exterior angles how many sides does it have?
1 a circle 360 interior angles 360 exterior agles
How do you solve for the interior angle using only the exterior angle?
a circle is 360 degrees. so whatever exterior angle u have u can subtract it from 360 to see what the interior angle is!
What is the opposite of the word interior?
The opposite of exterior is interior meaning inside
What is perimeter of a circle called?
The length of the perimeter is the circumference. The perimeter itself is the boundary between the interior and exterior of the circle. The perimeter of a circle is called the circumference
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 interior and exterior measures for a 9 sided shape?
Interior: 140 Exterior: 40
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 exterior clipping?
. Interior and exterior clipping interior clipping what is to be saved is inside the clip window exterior clipping what is to be saved is outside clip window Interior clipping
What is the answer of the polygon interior angle is five times the size of exterior?
Interior + Exterior = 180 and Interior = 5*Exterior So interior = 150 degrees and exterior = 30 degrees. Nothing more may be said unless it is known that the polygon is regular.
Is a 45 degree angle interior or exterior?
Exterior
What is the interior and exterior of a regular nonagon?
