180(n-2)=n*144 in our case

solving for n we obtain:

36n = 360

n=10 sides

CHECK!!!!!!!!!!!!!!!!!!!

solving for n we obtain:

36n = 360

n=10 sides

CHECK!!!!!!!!!!!!!!!!!!!

A square - but the "no angles" is the clincher. Unless (4) 90 degree angles aren't considered angles.

Since there are an infinite number of polygons, I can't list all of their names. For the names of all polygons with up to 100 sides, see http://en.wikipedia.org/wiki/Polygon

This works for any polygon:

Say you have 2 squares - the sides are 5 and 9

Perimeter 1 = 20

Perimeter 2 = 36

20:36 = 5:9

What follows is true for CONVEX polygons.

Let**n **be the number of sides of a convex polygon, and let** n** **be greater than or equal to 4**, then

The number of diagonals is given by**n*(n-3)/2**

Using this rule, write**n*(n-3)/2**=20. Clear the fraction, open brackets. You end up with **n^2-3n-40=0**.

Factor the polynomial or use the formulas for the quadratic equation to find the roots as** n=-5 or n=8**. Discard the negative root because n must be positive.

Let

For convex polygons there is a relation linking the number of sides to the number of diagonals. Here it is, with n=number of sides

**number of diagonals=n*(n-3)/2.** Obviously the number of sides must be greater or equal to 3.

If you use the relation for a hexagon (n=6) the number of diagonals is 9. With n=7, the number of diagonals is 14, and for n=8 the number of diagonals is 8*(8-3)/2=20.** The answer is that there does not exist a CONVEX polygon with 15 diagonals.**

You can also try to solve the quadratic equation n(n-3)/2=15 for a positive integer. And you will not find a solution.

For polygons that are not convex there may be many solutions or no solutions. I leave that to you as an exercise.

A **convex polygon** is one with each of its interior angles less than 180 degrees and every line segment between any of its two vertices remains inside or on the boundary of the polygon.

Example of a convex polygon (WIKIPEDIA)

A**concave polygon** will always possess an interior angle with a measure that is greater than 180 degrees.

SC-320 Polygon mirror motor error:

Symptom: Did not detect lock signal from

polygon mirror motor within 10

seconds after motor ON signal;

or, lost lock signal for

continuous 1.5 seconds after

signal was detected.

Cause:

1.Polygon mirror motor (or harness)

defective

2.FCU defective

P.S. Remove LSU. Turn out poligon mirror.

Clean & lubricate.
