How do you find the missing exterior angles?
take away the interior angle adjacent to it from 360
How many interior angles in a pentacontagon?
50 internal angles though it will take some time to work out what they are.
What is the sum of the measure of the interior angles of the convex 10 gon?
It is 8 x180=1440 degrees. Take an n-gon and the measure of the interior angles is (n-2)x180 degrees.
What does it take to make a triangle congruent?
The 3 sides are the same length and the 3 interior angles are the same.
Why is the sum of the exterior angles of any polygon 360?
There is no 'why' because this is not true. Just take a triangle for example. The sum of the exterior angles is 360, but that is not the only polygon. Now take a square. The sum of the exterior angles is 1080. So your statement is not true for a square, rectangle, parallelogram, lots of other polygons.

Given an interior angle how do you find the sum of exterior angles of a polygon?
Given a shape as such... ______________________________________ / A=72 B=65 \ \ / \_C=105__________________D=110_______/ (sorta) You take the interior angles that you have and subtract them from 360 to get their supplementary angles, which would be the measure of the outside angles corresponding to the interior angles Measure of <A= 72- so 360- 72=288*; so the measure of the exterior angle corresponding to <A is 288* You can do the same thing for the rest of the angles in the polygon. Hope it helps...

How many triangle doese it take to make a rhombus?
2 triangles make up a rhombus which has 4 interior angles adding to 360 degrees and a triangles has 3 interior angles add up to 180 degrees. Therefore: 360/180 = 2 triangles
What is the area of an hexagon if the interior angles are 120 degrees?
It probably is a regular hexagon. Take the Apothem (The distance from the center to a side) and multiply by one half and by the perimeter. if the sum of interior angles of a polygon is 120 then (n-2)180=120==>n=8/3 which is impossible
How many degrees in the external angles of a hexagon?
To work out the inside angles, do the number of sides (6) minus 2 (=4) multiplied by 180. *Quick mental calculation* (=720). This is all the interior angles added together, so quickly divide it by 6, which is the number of individual interior angles (=120).Now, do you know you're angles i a straight line? Well, good. Simply take 120 away from 180 (=60) Andd there you have it. The exterior angles of a hexagon are each 60 degrees.* * * * *True, but here is a much simpler answer:The exterior angles of ANY polygon add to 360 degrees. If the polygon is a regular (all angles equal) hexagon (six of them) then each exterior angle is 360/6 = 60 degrees.
How do you find the interior angles of a octagon?
if you are talking about a regular octagon. or any polygon, Take the number of sides ( 8 for an Octagon) minus 2 and multiply by 180 for the total of all interior angles. (8-2)180 = 1080 divide this by the 8 angles for the measure of each individual angle. 1080/8 = 135 By the way a "regular" polygon is one where all the sides and angles are the same. Good luck.
How many degrees are in one side of a hexagon?
regular hexagon has six sides of equal length, each couple intersecting to form a vertex of which there are six. A polygon has six internal angles of equal measure and has six external angles of equal measure.External angles= angles on the outsideInterior angles= angles on the inside(of the shape.)For a hexagon you'd do 360/6 (because it has 6 corners/angles) which = 60, that is the exterior angle, to find the interior angle you'd take 60 away from 180 because that's how many degrees are on a straight line, which would make it 120 degrees
What are the parts of a trapezoid?
It is a quadrilateral because it has 4 sides 2 of which are parallel and it can also take the form as an isosceles trapezoid. It has 4 interior angles that add up to 360 degrees.
