Do you calculate the interior angles of regular and irregular polygons the same way using the number of sides - 2 times 180 degrees n-2180 sum of interior angles. A Pentagon would 5-2?

All triangles have 180 degrees, all quadrilaterals have 360 degrees, no matter what the kind of triangle or quadrilateral. The formula would hold true for all polygons. Prove this by drawing diagonal lines in a polygon (do not cross one diagonal with another) to divide the polygon into quadrilaterals and/or triangles. Then add the degrees in the quadrilaterals and triangles in your polygon. This should give you the correct number of degrees. If you have a many sided polygon, it is necessary to use the formula, because the figure would be very difficult to draw. Formula- Number of sides minus 2, times 180 degrees. (n-2) X 180= degrees in a polygon

How do I find the area of irregular shaped polygons?
For instance, you might divide the polygons into triangles, calculate the area of each triangle, and then add everything up.
Why do shapes tessellate?
Shapes tessellate to fit around an interior angle. They also tessellate because they are regular polygons; non-regular polygons cannot tessellate. * * * * * Not correct. All triangles and quadrilaterals will tessellate, whether regular or irregular. Contrary to the above answer, a regular pentagon will not tessellate but there are 14 different irregular pentagons which will tessellate (the last was discovered in 2015). Three convex hexagons will do so as well. No polygon of 7 or more sides will tessellate - whether they are regular (contrary to the above answer) or irregular.
Can irregular polygons tessellate?
Some can, but not all. For example, rhombi, rhomboids, oblongs, and isosceles triangles can tessellate; however, most irregular polygons cannot. * * * * * True, but an incomplete answer. All triangles and quadrilaterals, whether regular or irregular, will tessellate. No regular pentagon will tessellate but (as of 2016), there are 15 irregular pentagons which will tessellate. There are 3 convex hexagons, (regular and 2 irregular) which will tessellate. No polygon with 7 or more sides, even if it is regular, will tessellate.
What is the difference between regular and irregular triangles?
Regular polygons have all equal length sides and irregular polygons do not.
A scalene triangle and a trapezoid are both what polygons?
They are both irregular polygons
What two polygons have five vertices?
They are a regular pentagon and an irregular pentagon.
Which regular polygons has the larger interior angle pentagon or square?
pentagon
Which of these two regular polygons has the larger interior square or pentagon?
Each interior angle of a square is 90 degrees Each interior angle of a regular pentagon is 108 degrees
What polygon has five sides that is not a pentagon?
An irregular pentagon, which is still a pentagon, just not equal angles or sides. All 5 sided polygons are called pentagons.
What are all the irregular polygons called?
Irregular polygons.
Is a pentagon a regular polygon sometimes always or never?
All polygons can be irregular sense the requirements for a polygon to be irregular is for 1 or more sides to be unequal to the others. So a pentagon is sometimes a regular polygon. Hope that answers your question.
What are the are the kinds of a polygon?
There are several types of polygons, including regular polygons, which have equal sides and angles, such as a square or equilateral triangle. There are also irregular polygons, which have different side lengths and angles, such as a rectangle or pentagon. Finally, there are convex polygons, where all interior angles are less than 180 degrees, and concave polygons, where at least one interior angle is greater than 180 degrees.
what is the name of polygons you given to a shape?
There are lots of different types of polygons Polygons are classified into various types based on the number of sides and measures of the angles.: Regular Polygons Irregular Polygons Concave Polygons Convex Polygons Trigons Quadrilateral Polygons Pentagon Polygons Hexagon Polygons Equilateral Polygons Equiangular Polygons
Which of these two regular polygons has the larger interior angle pentagon or square?
Each vertex angle of a polygon is composed of an external angle and an interior angle. These two angles are supplementary (total 180°). As the number of sides of a regular polygon increases then the external angle decreases and conversely, the interior angle increases. The interior angle of a regular pentagon (108°) is larger than the interior angle of a square (90°).
Is a pentagon an irregular polygon?
A Pentagon is a five sided polygon.There are two types of pentagon.One is the regular which all angles and sides are equalThe other is an irregular pentagon, which has different lengths of sides and different angles.However all pentagons must have an angle sum of 540 degrees to qualify it as a pentagon.So in answer to the question, some pentagons are irregular polygons while others are not.
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.
If a Polygon has odd number of angles angles cannot be congruent?
All regular polygons have equal lengths and equal interior angles but irregular polygons have variations in sizes.
