Tessellations of regular polygons can occur only when the external angle of a polygon is equal to a factor of 360. As such, the only tessellations of regular polygons can occur when the internal angles of a polygon are equal to a factor of 360. As such, the only regular polygons which tessellate are triangles, squares, and hexagons.
A reflex angle.
complete angle
A Full rotation
A circle has 360 degrees and a square has four 90 degree angles as does a rectangle.It's called complementary. A 90 degree angle is called supplementary.
The angle has to be a factor of 360 degrees
A 360 degree angle is a full turn

complete angle
A zero degree angle is not the same as a 180 degree angle -- no more than a90 degree angle is the same as a 270 degree angle.It's not. An angle of zero is the same as an angle of 360 degrees. In fact, if you startwith any angle, and add or subtract 360 degrees from it, you wind up with the sameangle as the original one.
Its not its the same as 360
A Full rotation
The sum of the angles in a trapezoid is 360 degrees, therefore, the forth angle in this problem is: 360 - (60+120+80) = 100 degrees

8 of them.
a quadrilateral has angles that add to 360
