Finding the diagonals of a polygon is a necessary skill to develop in math. It can be difficult at first, but it’s really simple once you learn the basics. A diagonal is the part of a line drawn between the vertices of a polygon that does not include the sides of that polygon.
A polygon is any shape with more than three sides. With a simple formula, you can count the number of diagonals in any polygon, whether it has 4 or 4000 sides.

To find out how many diagonals a polygon has, first count the number of sides, or lines, that make up the polygon. Then subtract 3 from the number of sides. Multiply this number by the number of sides. Finally, divide the result by 2 and you will have the number of diagonals in the polygon. For example, if a polygon has 6 sides, you will see that it has 9 diagonals. For another way to determine the number of diagonals in a polygon, read !Polygon; the word means “many angles”, but ignores one characteristic: the straight side. Polygons around us! Learning about these basic plane shapes helps you understand geometry.
A polygon is a plane figure that fits into a space using only line segments. If you have to use only part of the line and have to fit in a space, the polygon with the fewest sides should be a triangle (three sides and an interior angle).
Polygons do not have an upper limit on the number of sides and internal angles, so mathematics says n-gon after the common name we use for regular polygons.
You can also use abbreviations like this: 19-gon, 23-gon. Most math students, teachers, and mathematicians use n-gon for polygons with more than 12 sides and angles.
Ex 3.1, 5
Let’s take a closer look at regular polygons. A regular polygon is one in which all sides are equal in length and all angles are also equal in length. Next time you’re driving, look closely at the stop signs. A stop sign is an example of a regular polygon with eight equal sides.
No matter which way you look at a regular polygon, you won’t know which one is up because all the angles and sides are the same.
Look at these regular polygons. Have you noticed that all sides and corners are somehow the same?
The interior angles of polygons are the vertices, or interior angles, formed by the ends of the lines. Connecting all the vertices in a regular polygon without crossing lines creates a triangle.

, so one way to find the sum of interior angles is to count the number of dividing triangles:
All interior angles of a regular polygon are equal (interior angles are congruent). Once you know how to find the sum of an interior angle, you can use it to find the measure of an interior angle,
Let’s try an equilateral triangle by adding 3 to the number of sides (
Both versions will give you the same answer. See the second part of this version,
Finding Interior Angles Of Polygons — Krista King Math
All polygons have the same number of interior and exterior angles. A triangle has three exterior angles; there are four squares; his nonago has nine.
An exterior angle is an angle formed outside the polygon between one side and the line extending from the adjacent side of the polygon. The interior and exterior angles will continue to increase
With irregular polygons, you have no way of knowing the dimensions of the exterior angles. In regular polygons with
On the other hand, you can use a formula to find the exterior angles of the shape, because they will match:
Solved Problem 9.10 What Should Be The Sum Of The Exterior
Return to the second version of the formula for finding interior angles of regular polygons, which we wrote:
Now you can see that the two formulas make sense together because one finds the supplementary angle of the other.
You should now be able to identify and describe polygons and regular polygons, find the sum of the interior angles of regular and irregular polygons, and find the interior and exterior angles of regular polygons. You can use formulas to find the sum of the interior angles of any polygon and to know the actual measures of the interior and exterior angles of a regular polygon.

Parallel sides, lines, lines, and rays are two lines that are always equidistant and never meet. For a line, only the line passing through a point not on the line is parallel to it, like this:
Even if we drag these two lines to the left and right as far as possible (to infinity!), the distance will be the same. This means they are parallel.
Or a polygon can have two parallel sides, two parallel sides, like this square and rectangle:
Three Dimensional Shapes
Any regular polygon with equal sides will have two adjacent sides. A regular polygon will have half of its sides parallel (because the two sides form a pair).
This is an interesting property of regular polygons and parallelograms. A regular dodecagon (12 sides) will have six parallel sides, while a regular tridecagon (13 sides) will have
The parallel sides of a square, or any polygon, must be straight sides. They can be the same length, but they don’t have to be.
Another characteristic of parallel sides of polygons is that the distance between two adjacent sides will never change, even if we lengthen the shape:
Ways To Find The Area Of A Quadrilateral
You can point to adjacent sides, even if your drawing isn’t perfect. You can also write about straight lines or parallel sides with symbols.
When drawing, indicate pairs of parallel sides by drawing small arrows parallel to the two adjacent sides.
If you have, for example, a rectangle (with two parallel sides), you can use a single arrowhead for one pair and two arrowheads for the other:
Many geometricians like this symbol because it cannot be confused with the letter 11 L or two. Here we use the parallel symbol to represent this line
How To Find How Many Diagonals Are In A Polygon: 11 Steps
You see, if we write the letter l, it will look like “baller”, which is useless without a game.
In a polygon, you can test for parallel sides by checking the notation (the small arrow), measuring between the two lines in question, or applying Euclid’s parallel line test .
If you choose to measure the distance between two sides, make sure to measure the line parallel to the two sides, not the angle. Measuring the vertices of a trapezoid, for example, will not provide clear evidence that the two bases (upper and lower) intersect, because the vertices may be different.
How do you prove that lines are parallel? Euclid’s Courage is also useful, because you can prove parallel lines using one of the following methods:
