In mathematics—namely geometry—and in real life, geometric shapes are two or three-dimensional figures that can be recognized and categorized based on a specific outline/boundary and other attributes including curves, lines, and angles.
Shapes can be classified into open and closed shapes. In geometry , an open shape can be defined as a shape or figure whose line segments and/or curves do not meet.
Jun 30, 2024 · Polygon is a closed curve which is made up of only finite number of line segments and any two line segments do not intersect each other except at their end points. It is a two dimensional figure in geometry. The line segments of a polygon are called sides or edges and end points of the line segments are called its vertices or corners.
- A closed plane figure formed by line segments and two line segments which intersect at only their end points.
- The sum of angles of polygon with n sides is (n-2)180 0 .
- Sum of exterior angles of polygon is 360 0 .
- Yes, equilateral triangle is a regular polygon as its all sides are equal and all its angles are equal.
- No, rectangle is not a regular polygon as its angles are equal but all sides are not equal.
Aug 12, 2022 · Two points on a plane determine a line. A line is a one-dimensional figure that is made up of an infinite number of individual points placed side by side. In geometry, all lines are assumed to be straight; if they bend they are called a curve. A line continues infinitely in two directions.
Identify open and closed shapes based on the following properties: Open Shapes: Open shapes are not continuous and are made up of line segments or curves which do not meet. Closed Shapes: Closed shapes can be traced without any break. They start and end in the same place.
Nov 4, 2024 · Curved shapes are composed of continuous curved lines. For example, a circle, ellipse and oval are all curved shapes. Curved shapes have no fixed sides or vertices, and have a radius of curvature at each point around the shape.

Frequently Asked Questions. Geometric Shapes Definition. Geometric shapes are closed figures created using points, line segments, circles, and curves. Such shapes can be seen everywhere around us. Some of the geometric shape examples are circle, rectangle, triangle, etc. A pizza is circular, whose slices are triangular.
