The size of the angle would depend on the shape and number of sides the polygon has. It is called the exterior angle.
Exterior angles are 7.5 There are 48 sides.
exterior angle = 360° ÷ 20 sides = 18° interior angle = 180° - exterior angle = 180° - 18° = 162°
Rhombus. Because a rhombus has congruent (egual in shape and size) sides, but has no right angles.
The sum total of all exterior angles of any polygon is 360 degrees. So if you're given thevalue of one exterior angle AND THE POLYGON IS REGULAR(all exterior angles are thesame size), all you have to do is divide the size of one angle into 360, and the quotientis the number of sides.
The length of it's sides
No because each interior angle increases in size whereas each exterior angle decreases in size.
No because a quadrilateral has 4 sides whereas a triangle has 3 sides.

Each interior angle is: 1520 18' 27.69''
Each interior angle is: 1540 17' 8.57''
Each interior angle: 1640 20' 52.17''
Divide the number of sides into 360 which will give you the exterior angle and subtract this angle from 180 which will give you the interior angle.
150 degrees
The sum of the exterior angles of a polygon is 360o. Dividing 360o by the size of the exterior angle gives the number of sides. If the interior angle is 144o, the exterior angle is 180o - 144o = 36o. Number of sides = 360o / 36o = 10 (a decagon).
Each external angle is equal to 360/n degrees where n is the number of sides (or angles) of the polygon. So the external angle is inversely proportional to the number of sides.
There can be as many sizes as you want but the right angle always has an 90 degree angle in it but the length of the sides can be varied (they can be as long as or as short as you want). :)
