Introduction for Unequal Angles: Geometric shapes play an important role in mathematics. Triangle is a geometric figure with 3 sides. Mostly the three sides of a triangle are equal. The angles are correspondence to the triangle. In some cases, the angles of the triangle are unequal. Those triangles are called Scalene Triangle. Scalene triangle is the geometric shape, which has unequal angles. Let us discuss about the Unequal angles of various geometric shapes. Polygon with Unequal Angles: A polygon is distinct as any plane figure, which is enclosed that has n straight sides or n corners. A polygon is a multiple sided plane figure. When the angles of any polygon are unequal, then it is said to be irregular polygon. Representing the Unequal angles of a Triangle: unequal angles of triangle In these Triangles, the side lengths are different and the three angles are unequal. In the figure(1), one of the angles is 90 degree, and other two are different. These types of triangles are Scalene Right Triangle. In figure (2) and figure (3), three angles are different respectively. Irregular Quadrilateral (Unequal angles): A 2-dimensional closed shape with four straight sides is a Quadrilateral. Irregular quadrilateral The 4 sided shape is a Quadrilateral. The irregular quadrilateral has 4 sides with different angles and side lengths are also different. An irregular quadrilateral which does not possess any special properties. Some other Polygon with Unequal Angle: Pentagon: The pentagon, which has five sides. Pentagon with equal angles Here the angle of the pentagon will be equal. Pentagon with unequal angles This is a pentagon with unequal angles. Hexagon: The hexagon has five sides. Hexagon with equal angles Here the angle of the hexagon will be equal. Hexagon with unequal angles This is a hexagon with unequal angles. Symmetry: If the angles of the polygons are irregular, then it does not have any symmetry lines. Any polygon that is not a regular polygon, whose sides are not all the same length or whose interior angles do not all have the same measure.
