There is no polygon with a total angle measure of 200 degrees. The sum of angle measures of a polygon equals to [180 degrees(n - 2)], where n is the number of its sides and n is at least 3.
triangle
A four-sided polygon with opposite sides parallel could be a square, a rectangle, or a rhombus.If it has one pair of opposite, parallel sides, then it is a trapezoid. If it has two pairs of opposite, parallel sides, then it is a parallelogram.
No. A parallelogram, for example, is not a regular polygon. Even a rhombus, with parallel sides of equal lengths is not.
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
Trapezoid. It has two parallel lines on opposite sides.
parallogram or quadrilateril
B. False
Any polygon with an even number of sides can have opposite sides that are congruent and parallel.
Any even sided irregular polygon can have opposite sides parallel. A parallelogram would be the simplest of these.
A square.
a trapezoid
There is no particular name. It need not be a regular polygon - for example, consider a stretched hexagon.
