Now you can make a figure that the ball cannot escape. Each of the straight lines we used now act as a part of the figure. We will call each straight line a side of the figure. So, this figure has three sides and is called a triangle. When we say “triangle” we are either referring to how to arrange the three lines or the enclosing space.
Each geometric shape has a unique name (ex. rectangle, square, oval, etc) and geometrical shapes can be easily identified by looking at an image and seeing the shape’s characteristics, such as number of sides, angles, curves, or points. In fact, geometric shapes are all around you all of the time. Figure 01 below shows examples of common 2D ...
A rectilinear figure is a 2D geometric shape that can be drawn only using straight line segments. The word “rectilinear” means “consisting of straight lines” or “moving on a straight line.”. The edges of a rectilinear figure are line segments. A rectilinear figure can be open, closed, simple, or complex. The most common examples of ...
- No, a circle is not a rectilinear figure since one such figure should be made of straight lines.
- No, a cube is not a rectilinear figure since it is a 3D shape. Rectilinear shapes are plane, 2D shapes.
- A shape must have a minimum of 3 sides to be classified as a polygon.
- A rectilinear figure is made of straight lines and may be open or closed.
Jul 15, 2024 · As the name suggests, curved 2D shapes are closed figures formed by purely curved lines or a combination of straight lines and curved lines. As discussed earlier, all curved 2D shapes are also considered non-polygons. The most common examples of such geometric shapes are circles, ellipses, arcs, sectors, segments, parabolas, and hyperbolas.
This is because straight lines are the basis for finding some figures we often find in the real world: geometric shapes. Geometric shapes refer to planar surfaces limited by lines that can be curved or straight. To help you understand better, we are going to explain with an example. We will start with something simple: two straight lines.
A geometric shape is an object with a fixed structure. These shapes are made up of lines, curves, angles, and surfaces. Some of the known geometric shapes are square, rectangle, circle, cylinder, etc. A polygon is a geometric shape with 3 or more sides. Some of the common polygons are triangle, square, rhombus, trapezium, etc.

Lines are defined as a collection of points. In other words, many points are put together to form a line. They may form a straight line or a curved line. Shapes are closed shapes that are created by joining lines together. Closed shapes made of four straight lines are called quadrilateral shapes. Here is a list of shapes with real-world examples.
