DefinitionIn Euclidean geometry, triangles, quadrilaterals, and circles are the main basic geometric shapes. Triangles have three sides, and the sum of their three angles is 180 degrees; quadrilaterals have four sides, and a circle is a collection of points equidistant from a center. These formed shapes have their respective properties, formulas, and relationships which are vital in the realms of geometry, trigonometry, and calculus. These have a wide range of applications including architecture, engineering, and art. For example; The Pythagorean theorem says that in a right triangle, the sum of the sides a and b squared equals the side c squared Learn and solve Basic Shapes (Triangles, Quadrilaterals, Circles)
