What is the sum of a convex polygons exterior angles?
Remember that the internal angle of a regular convex polygon is (n - 2) * 180 degrees / n, where n is the number of sides in the polygon. Also remember that the external angle of a regular convex polygon is 180 degrees minus the internal angle a polygon. So the external angle of a polygon is 180 - ((n - 2) * 180 / n). The sum of the angles will be the external angle multiplied by n, or: (180 - ((n - 2) * 180) / n ) * n = 180 * n - (n - 2) * 180 Please note that I only proved this for regular polygons, but this formula should also extend to irregular convex polygons too. If a teacher asks you for a proof, then this will be insufficient.
Why do All polygons have exterior angles that sum to 360 degrees?
Only convex man, if the angle is concave it would not be 360 degree.
What to regular polygons has a larger exterior angle?
An equilateral triangle is the only polygon in which the exterior angle is larger than the interior angle. They are equal in a square and smaller in all regular polygons with more sides,
Which of the polygons cannot be used to create a pure tessellation?
The only regular polygons which will tessellate are those with 3, 4 or 6 sides. But all irregular triangles, all irregular quadrilaterals, 15 classes of irregular convex pentagons and 3 classes of irregular convex hexagons will tessellate. In addition, there are concave polygons with different numbers of sides which will also tessellate.
If the measure of one interior angle of a regular polygon is 90 degrees how many sides does the polygon have?
The only regular polygon with an interior angle of 90 degrees is the square, which has four sides. Other polygons can have an interior angle of 90 degrees, but they would not be regular polygons.

What convex figure has exterior angle measure of 72 degrees?
Any convex figure can have an exterior angle measuring 72 degrees. If you consider only regular polygons, then it wuld be a polygon with 360/72 = 5 sides, that is, a pentagon.

If the measure of one interior angle of a regular polygon is 90 degrees how many sides does the polygon have?
The only regular polygon with an interior angle of 90 degrees is the square, which has four sides. Other polygons can have an interior angle of 90 degrees, but they would not be regular polygons.
How many types of tessellations are?
Tessellations of regular polygons can occur only when the external angle of a polygon is equal to a factor of 360. As such, the only tessellations of regular polygons can occur when the internal angles of a polygon are equal to a factor of 360. As such, the only regular polygons which tessellate are triangles, squares, and hexagons.
What polygons has the larger exterior angle?
A polygon with any number of sides can have an exterior angle that is larger than the corresponding interior angle. However, a triangle is the only regular polygon where the exterior angle is larger.
What are the different kinds of polygons and their interior angle?
Polygons can be classified in a number of ways. A convex polygon is one in which a straight line joining any two points inside the polygon lies wholly inside the polygon. One consequence is that all its interior angles are less than 180 degrees. A concave polygon is one in which at least one angle is a reflex angle (> 180 deg). Generally, a polygon may be assumed to be convex unless otherwise specified. A regular polygon is one in which all the sides are of equal length AND all the angles are of equal measure. An irregular polygon is one in which at least one side is of a different length from the others OR at least one angle is of a different measure from the others. Polygons can have three or more sides. There is no limit to the number of sides that a polygon may have. The interior angle of a polygon is pre-determined only if it is regular. In a regular polygon with n sides, each interior angle has a measure of 180*(n-2)/n degrees. A regular triangle [equilateral] is acute angled; a regular quadrilateral [square] is right angled and all other regular polygons are obtuse angled.
Will all polygons tessellate?
No because only polygons whose interior angles are a factor of 360 will tessellate. For instance a regular pentagon will not tessellate because its interior angle is 108 degrees but a hexagon will tessellate because its interior angle is 120 degrees which is a factor of 360.
What polygon has no right angle?
There is only one regular polygon which contains right angles - this is a square. None of the other regular polygons from 3 sides and upwards has a right angle.
Is there a formula for determining degrees for an acute angle?
There isn't a formula for determining the degrees of a simple acute angle. The only way is with a protractor or estimate.
