Antonyms of a triangle refers to geometric shapes that are not triangles. Triangles are polygons with three sides and three angles. In contrast, antonyms of triangles are shapes that have more or less than three sides and angles.
Polygons with more than three sides are known as polygons, while those with fewer sides are called lines or line segments. Circles, ellipses, and quadrilaterals are common examples of shapes that are antonyms of triangles. These shapes do not have the defining characteristics of a triangle – specifically, the presence of three sides and three angles.
Understanding the antonyms of a triangle is essential in geometry, as it helps in identifying and differentiating various shapes based on their unique properties. By recognizing shapes that do not fall under the category of a triangle, one can enhance their knowledge of geometry and geometric relationships.

Antonyms of triangle, opposite of triangle and triangle ka opposite word are the same thing. In conclusion, the opposite word of triangle is circle, a figure with a curved line that does not have any corners or angles. While a triangle is made up of three sides and three angles, a circle is defined by its continuous, round shape with no sides or angles. These two shapes are distinct in their characteristics and properties, serving different purposes in various mathematical and practical applications.
Understanding the contrasting features of a circle and a triangle can enhance our mathematical comprehension and problem-solving skills. By recognizing the unique attributes of each shape, we can effectively utilize them in different contexts and scenarios. The distinction between a triangle and a circle highlights the diversity and richness of geometric shapes, contributing to a deeper understanding of mathematical concepts and relationships.
