What is the sum of a 4 sided polygon?
360°A quadrilateral is a polygon which has 4 vertices and 4 sides enclosing 4 angles and the sum of all the angles is 360°. When we draw a draw the diagonals to the quadrilateral, it forms two triangles. Both these triangles have an angle sum of 180°. Therefore, the total angle sum of the quadrilateral is 360°.
What is the sum of the exterior angles of a 4 Gon?
The sum of exterior angles formula says the sum of all exterior angles in any polygon is 360°.

What is the sum of a 5 gon?
In geometry, a pentagon (from the Greek πέντε pente meaning five and γωνία gonia meaning angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting.
How do you solve a polygon?
The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides. The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.

What is the sum of a 20-Gon?
3240 degreesIn geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon's interior angles is 3240 degrees.
What is the sum of a 18 gon?
Therefore the sum of the interior angles of an 18 sided polygon is 2880∘ .
How many degrees is a 4 sided polygon?
360 degreesThe common property for all the above four-sided shapes is the sum of interior angles is always equal to 360 degrees. For a regular quadrilateral such as square, each interior angle will be equal to: 360/4 = 90 degrees.
What is the shape with 4 sides?
quadrilateralA quadrilateral is a 4 sided closed figure. These figures are quadrilaterals: A shape with four sides. The shape has one set of parallel sides and does not have any right angles.
What is the sum of a 6 sided polygon?
The sum of the interior angles of a hexagon must equal 720 degrees. Because the hexagon is regular, all of the interior angles will have the same measure. A hexagon has six sides and six interior angles.
What is the measure of each exterior angle of a polygon with 4 sides?
The measure of each exterior angle of a regular polygon is given by; The measure of each exterior angle =360°/n, where n = number of sides of a polygon. One important property about a regular polygon's exterior angles is that the sum of the measures of the exterior angles of a polygon is always 360°.
Is the sum of exterior angles always 360?
The sum of the exterior angles of any polygon (remember only convex polygons are being discussed here) is 360 degrees. This is a result of the interior angles summing to 180(n-2) degrees and each exterior angle being, by definition, supplementary to its interior angle.
Why exterior angles add up to 360?
We also know that in a triangle, the interior angle and its corresponding exterior angle form a linear pair, i.e., Exterior angle = 180° - Interior angle. Hence, the sum of exterior angles of an equilateral triangle is equal to 360 degrees.
What's the sum of exterior angles of a polygon?
360°If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360° .
