Geometrical shapes are all around us. They make up the form and structure of every two-dimensional (2D) and three-dimensional (3D) object. 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.
1. Straight Lines: There are three different types of straight lines. (i) Horizontal lines, (ii) Vertical lines and (iii) Oblique or slanting lines. Straight lines can be drawn horizontally, vertically and slanting. Observe the edge of this page. Place a ruler along its edge.
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.
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.
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.
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 ...

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.
