What are the two types of geometry?
Geometry is a part of mathematics that deals with the relationships of points, lines, angles, surfaces, solids measurement, and properties. There are two types of geometry: 2D or plane geometry and 3D or solid geometry. 2D shapes are flat shapes that have only two dimensions, length, and width as in squares, circles, and triangles, etc. 3D objects are solid objects, that have three dimensions, length, width, and height or depth, as in a cube, cuboid, sphere, cylinder, cone, Let us learn geometry formulas along with a few solved examples in the upcoming sections.

The Sphere. Our earth is a sphere as can be seen from outer space and also through a model of a globe. The calculation of points of location on the earth using longitude and latitude is based on the degree of a circle. The other planets are also spherical in shape.
Geometric Shapes Definition
Real-Life Applications of Geometric Shapes
- Geometry is the study of shape and space. It helps us understand other mathematical concepts as well as real-life applications. Geometry can be used for designing buildings, bridges, cars, and even clothes. The principles of geometry are also used in other branches of mathematics, such as trigonometry and calculus. The following are some of the real-life applications: Squares: Square…
Examples of Three-Dimensional Shapes
- Three-dimensional shapes are a group of vertices, lines that connect the vertices, and faces enclosed by these lines. They have length, breadth, and height and they occupy some volume. For many three-dimensional shapes, faces are two-dimensional. Also, some shapes in three dimensions have curved surfaces. In three dimensions, the primary shapes are: 1. Cube: Rubik’s …
Solved Examples
- Example 1: How many sides does a decagon have? Solution: A decagon has ten sides and ten vertices. Example 2: What is a triangle with only two sides equal called?
