What is Geometry?

Understanding geometry can be difficult. With so many sub-topics under the umbrella of Geometry it can be difficult to grasp what exactly is Geometry, why and when could ever be useful? Generally speaking, Geometry is study of shapes – how they can be transformed, scaled, measuring/calculating the angles found within them, as well as other characteristics such as area, volume, and so forth. The study of Geometry also involves the study of lines, the building blocks of shapes, and their properties. Here at StudyPug, Geometry will also introduce you to the realm of statistics where we look at probability, and how this is to shapes (i.e. Venn diagrams).

Who is known as the father of geometry?

The honour and prestige of this title was bestowed to the one and only Euclid of Alexandria. He was an incredible Mathematician who studied at Plato's Academy in Greece and the first to study Geometry. He went on to publish a variety of textbooks used by mathematicians to this day. He is most known for his work on a publication titled "The Elements" that feature ground-breaking content on algebra, number theories, and of course, geometry. It is said that this masterpiece was what earned him the title of "Father of Geometry" (

Is geometry hard?

Studying Geometry can have its challenges and learning curves, but that's why we're here! Here at StudyPug, we offer help for all - those who fall under the category of Geometry for dummies or those who are looking for more practice and/or advanced questions. At StudyPug we strive to make learning geometry easy, accessible, and engaging. With over 1000's of lessons, Step-by-step examples, and 24/7 help, we are prepared to help students with endless opportunities for easy practice, be it for Geometry exam preparation or to simply to reinforce learning. Here at StudyPug we cover a wide variety of questions you may encounter and we also use a variety of Geometry textbooks (e.g. Prentice Hall Geometry; Glencoe Geometry; McDougal Littell Geometry; Big Ideas Math Geometry) to cater comprehensively to the content you may be learning. Rest assured, we're well equipped to help with the fundamental concepts and basic problems that will allow you to progress confidently to more complex, challenging questions at your own pace.

What is Euclidean geometry?

Euclidean geometry is the branch of geometry that is focused on the study of 2-dimension solid geometry and planes. Some examples include basic facts such as the interior angles of triangles should equal to 180 degrees and that the shortest distance between point A and B is a straight line. Euclidean geometry was built on the basis of Euclid mathematical theories and postulates, most notably composed and synthesized in his publication "The Elements". In a broader sense, Euclidean geometry is also referred to the importance of utilizing cognitive abilities in Math. This encompasses the learner to defer techniques of memorization and formulas, and to rely on a strong, holistic understanding of the subject that allows application of skills and techniques to solve Math problems. While you may have begun studying Euclidean geometry early on in school, you will soon begin exploring concepts of non-euclidean geometry (e.g. properties of 3D shapes, such as a sphere).

How to pass geometry?

Whether you're preparing for a Geometry test, exam, or simply require Geometry help, StudyPug is here to help you succeed and pass your assessments through our Geometry tutoring and Geometry lessons. Our Geometry tutors will cover content, study tips, strategies, and practice questions that will provide you with as much help with Geometry as you need. We recommend starting with the difficult sub-topics/chapters you are struggling with, follow our Geometry tutorials as we take you step-by-step through the process of understanding a concept or problem you may have. Some concepts or problems are trickier than others so you may need to revisit theses areas more than once, which shouldn't be a problem given your unlimited, 24/7 access. Once you are feeling confident, we encourage you to practice, practice, practice! This enables you to be prepared for different styles of questions as well as different levels of difficulty. These questions will supplement your learning and truly test your understanding.

What grade is geometry?

Students begin learning Geometry in 10th Grade. Students should have a strong understanding of Algebra 1 (completed in 9th Grade) before beginning to tackle topics covered in Geometry. For a refresher, please see our Algebra 1 page. Following the completion of Geometry, students may proceed to beginning Algebra 2. Ahead of the game? Wonder what comes after Geometry? Visit our Algebra 2 page for more learning.

  • My Geometry textbook is by McDougal Littell. Can your geometry course help?

    Of course! We cover all the topics in your textbook. Our geometry class also contains help on all materials you will find in other common textbooks, such as Holt McDougal Geometry, Glencoe Geometry, Prentice Hall Geometry, and Pearson textbook.

  • I am taking high school geometry. How do I know if this course is relevant to what I am learning from school?

    We follow the Geometry common core standards closely when designing the course. Therefore, you will be able to find the geometry help on any topics which are taught in your school.

  • What are the prerequisites for Geometry?

    Course taken before this class is either Algebra 1 or Basic Algebra and after you mastered Geometry, you can follow up with courses like Algebra 2 or Trigonometry.
