Definition: The word "symmetrical" refers to a shape, structure or design where all sides are equal in length and angle, such as a square or circle. Here's a brief overview of the definition of "symmetrical": 1. Symmetry: It is the quality of being balanced or even with an equal distribution of weight. The word comes from Latin meaning "to have equality". In geometry, symmetry refers to the arrangement or arrangement of objects where all sides and angles are equal in length. 2. Equilateral: A type of triangle in which all three sides are the same length (equal). For example, a square with all equal side lengths is an equilateral triangle. 3. Scalene: It is one of the two types of triangles. In a scalene triangle, each angle measures 90 degrees and no side has equal angles. This type of triangle can also have sides that are not congruent to each other. 4. Isosceles: A triangle with two sides that measure the same length. An isosceles triangle has one angle measuring 60 degrees and all other angles measuring 30 degrees. It can be scalene or equilateral. 5. Right-angled: A type of right-angled triangle in which one of the angles measures 90 degrees. The side opposite to this angle (the hypotenuse) is always longer than the other two sides. 6. Obtuse: A type of triangle where an angle measures greater than 90 degrees and less than 180 degrees. An obtuse triangle has all three angles measuring more than 90 degrees. 7. Acute: A type of triangle where one of the angles measures less than 90 degrees (or is 90 degrees). An acute triangle has all three angles measuring less than 90 degrees. In summary, "symmetrical" refers to a shape or design that is balanced and even with equal sides and angles. There are different types of symmetries such as equilateral, scalene, isosceles, right-angled, obtuse, acute and many more.
