A triangle.
No, for a polygon to be regular it must have equal side lengths and angles.
It is an irregular polygon.
Angles outside a polygon, often referred to as exterior angles, are formed when a side of the polygon is extended. These angles are created between the extended side and the adjacent side of the polygon. The sum of the exterior angles of any polygon, regardless of the number of sides, is always 360 degrees. Each exterior angle can be calculated by subtracting the interior angle from 180 degrees.
a polygon with six sides and six angles is called a hexagon
Two angles of a polygon that have a common side.
A polygon has exactly as many sides as it has angles.
If measured on the inside of the polygon, the it is an interior angle.
There is a corresponding side to every angle. 20... A polygon has as many sides as it does angles.
A polygon has two types of measurements: side lengths and interior angles. The number of side lengths is equal to the number of sides the polygon has, while the number of interior angles is always equal to the number of sides. So, a polygon has two measurements: side lengths and interior angles.
