the center of the figure at the origin
-- Take the number of sides in the polygon. -- Subtract 2. -- Multiply the result by 180 degrees. -- You got it.
Subtract 1 from the number of vertices. Find the name of the polygon with that many sides. The pyramid has that polygon as its base. So, for example, 7 vertices. Subtract one and that gives 6. A six sided polygon is a hexagon. So the shape is a hexagon based (or hexagonal) pyramid.
It is a square which is a regular 4 sided polygon
If it is a regular polygon you count the number of sides. Subtract two and multiply that by 180. Then you would divide your product by however many sides there are
Depends how much is being added to which x-coordinate: If a constant amount is added to every x-coordinate, the polygon is translated (parallel to the x-axis). [This first possibility is what I think you are really asking, however:] If an amount is added which depends linearly upon the y-coordinate of the x-coordinate, the polygon is sheared (parallel to the x-axis). If an amount is added which depends linearly upon the x-coordinate, the polygon is stretched (parallel to the x-axis). If a random amount is added, the polygon is randomly transformed.

For any polygon: (number of sides-2)*180 = sum of interior angles
i can not tell you either
Subtract the interior angle from 180
-- Take the number of sides in the polygon. -- Subtract 2. -- Multiply the result by 180 degrees. -- You got it.
If you multiply 360 by the number of angles in the polygon and then subtract the sum of all the interior angles you will end up with the sum of all the exterior angles of the polygon.

plot the points (2,-2),(3,4),(-1,2),and (-2,-4) on the coodinate plane. connect the points, in order, to form a polygon. what kind of polygon is formed? be as specific as possible.
