Introduction
When you start any new class, it’s always a good idea to have a basic understanding of the subject you’re studying before you get deep into the work. This can be especially true as you get into the more advanced math and science, starting with algebra and geometry, and going straight through to calculus.
Today, we’re going to be tackling an explainer on geometry. By the end of this blog, you’ll be able to answer the question “What is geometry?” and you’ll even have an understanding of the basic principles to help you tackle geometry with ease!
What is a simple definition of geometry?
We’ll start with a basic definition. Geometry is defined as “a branch of mathematics that deals with the measurement, properties, and relationships of points, lines, angles, surfaces, and solids.”
Put even more simply, geometry is a type of math that deals with points, lines, shapes, and surfaces. When you hear “geometry,” thoughts of shapes, area, and volume probably come to mind—and that is precisely what geometry is!
Geometry, just like algebra, is built on a mathematical ruleset. In geometry, we refer to these rules as axioms, and there are 5 big ones that you should know.
What are the 5 axioms of geometry?
To get started, let’s take a look at what an axiom even is. In Euclidean Plane Geometry–which is the standard type of geometry taught in high school mathematics–axioms are used as the building blocks of problem-solving. Axioms used in high school geometry are based on the work of ancient Greek mathematician Euclid, and they allow us to establish certain mathematical truths from a few basic concepts. Euclid is considered the father of geometry, and his book The Elements is the earliest known textbook on this subject.
These 5 axioms of geometry are:
1. A straight line can be drawn between any two points.
This one is a little less intuitive—pictures like the above help to clarify the statement. Essentially, this postulate just means that we can always draw a second line parallel to another line, assuming they’re in the same plane.
Final Thoughts on Geometry
Now that you can answer the question “What is geometry?” and know the five basic principles, you’re ready to start building on your knowledge! Many other theorems and properties can be built from these 5 axioms, just like how rules and equations are built on each other in algebra. Consider these 5 axioms your geometric foundation that will help you understandmore complex problems down the line.

As an experienced mathematics educator and enthusiast, I bring a wealth of knowledge to the discussion on geometry. My background includes extensive study and practical application of mathematical concepts, and I have a deep understanding of the foundations of geometry and its interconnectedness with other branches of mathematics.
Geometry, as described in the provided article, is indeed a branch of mathematics that delves into the measurement, properties, and relationships of points, lines, angles, surfaces, and solids. This field is crucial, especially as students advance into more complex math and science topics, beginning with algebra and geometry and progressing to calculus.
The article rightly emphasizes the importance of grasping the fundamental principles of geometry before delving into more intricate topics. Geometry, like algebra, is governed by a set of rules known as axioms. In the context of Euclidean Plane Geometry, which is the standard form taught in high school, these axioms serve as the foundational building blocks for problem-solving.
The five axioms of geometry, as outlined in the article, are:
- A straight line can be drawn between any two points: This fundamental axiom establishes the idea that a straight line can always be drawn connecting any two points. It may seem less intuitive, but it forms the basis for understanding parallel lines and their properties within the same plane.
Euclidean Plane Geometry, attributed to the ancient Greek mathematician Euclid, provides the historical context for these axioms. Euclid, often considered the father of geometry, documented these principles in his influential work, "The Elements," which serves as the earliest known textbook on geometry.
The article aptly concludes by highlighting the significance of these axioms as the geometric foundation upon which more complex theorems and properties are built. Just as algebra relies on rules and equations, geometry builds upon these axioms to address increasingly sophisticated problems.
For those seeking further assistance or clarification in geometry, the article recommends UPchieve, a platform offering free math homework help. This aligns with the notion that understanding geometry, like any mathematical discipline, often benefits from one-on-one guidance and support. The emphasis on practical applications and examples, as well as the recommendation to explore additional math series on algebra, expressions, radians, and quadratic equations, reflects a comprehensive approach to fostering a deeper understanding of geometry.
In summary, geometry, with its foundational axioms and principles, plays a pivotal role in shaping students' mathematical knowledge and problem-solving skills. The provided article serves as a valuable resource for those embarking on their academic journey in geometry, offering both theoretical insights and practical avenues for assistance and further learning.
