Aug 12, 2022 · Geometric shapes, also called figures, are an important part of the study of geometry. The triangle is one of the basic shapes in geometry. It is the simplest shape within a classification of shapes called polygons. All triangles have three sides and three angles, but they come in many different shapes and sizes.
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 ...

Intersections
An intersectionoccurs when two geometric figures pass through each other. When this happens, the two figures are said to have intersected.
A proofin math is an argument used to show that a mathematical statement is true using postulates, theorems, and definitions. It “proves” that something is true. A postulate, also known as an axiom, is a statement that is known to be true, without evidence. We don’t have to prove it. A theoremis a statement that has been proven to be true using oth...
A polygonis a closed two-dimensional figure on a plane with at least three straight sides and no curved sides. Essentially, it’s any two dimensional shape without curves. So a triangle is a polygon, but a circle is not. Shapes with equal length sides and interior angles are known as Regular Polygons. If any of the interior angles or side lengths ar...
In this chapter, we have mentioned that congruent line segments have the same length. Congruence is the quality of two or more items having corresponding or agreeing properties. Congruent polygons are polygons with the same shape and size. Equality is the quality of two or more items being exactlythe same. Two line segments may be congruent, but th...
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. Similarly, doors and windows are examples of rectangles.
Geometric Shapes Examples: a triangle made by joining 3 lines and a circle made using a curve. Both the discussed examples are 2D geometric shapes. This means that these figures have only one plane and only two dimensions. The geometric shapes can be classified into two types based on their dimensions.
