Answer:
1. Regular Polygons: A regular polygon is equiangular (angle between any two vertices is equal) and equilateral (length of each vertices is equal).
2. x = 140°
3. 15 sides.
4. Regular and irregular polygon
Step by step explanation:
1. Regular Polygons: A regular polygon is equiangular (angle between any two vertices is equal) and equilateral (length of each vertices is equal).
2. Mark the given quadrilateral as ABCD, such that angleABC =70° angleBCD = 60°, to find x we need to find angleADC i.e. adjacent to 90°
Since, we know that, angle adjacent to a right angle is a right angle.
therefore, angleADC = 90°
Now, we know that sum of angles of a quadrilateral is 360°
therefore, angleABC + angleBCD + angleADC + x
70° + 60° + 90° + x = 360°
220° + x = 360°
x = 360° - 220°
x = 140°
3. Sum of exterior angle of polygon=360
Each exterior angle of polygon =24°
Number of sides of polygon=360°/24° =15
=> Number of sides of polygon with each angle of 24 is 15.
4. There are two main types of polygon - regular and irregular. A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides.
