# The Best Calculators for Geometry

By Kathleen Cantor, 02 Nov 2021

Out of all school supplies available to students, there is only one that we can always lean on when faced with challenging Mathematical problems. Calculators are one great invention that we are always grateful for in dealing with the different branches of mathematics such as algebra, trigonometry, and geometry. With these higher-level courses, there will come a point in our life as a student or a professional when we will need more than just a four-function calculator or even just a scientific calculator.

**What Is Geometry?**

Geometry is a branch of mathematics that deals with the size, shape, and position of 2-dimensional shapes and 3-dimensional figures. It is a focus that goes beyond arithmetic and algebra. Learning geometry will require the best tools, including a graphing calculator.

**Why Do I Need a Calculator for Geometry?**

While there are many online calculators available online, it is still best to consider investing in a tangible calculator. Without worrying about the limitations or monthly subscription fees, you can use its available functions all out and you will never have to worry when standardized tests come.

## The 5 Best Calculators for Geometry

If you are a student and you haven’t asked your teacher for recommendations yet, here are our top 5 picks for the best calculator for geometry.

**Conclusion**

Our top 2 picks which were from Texas Instruments are the best graphing calculator that we can recommend. The TI-Nspire CX II CAS and TI-84 Plus CE are capacitated with the best features there are for graphing calculators not only for Geometry but for almost all the higher-level Mathematics branches. Its quality will speak for its price.

**Frequently Asked Questions**

**What can I do with a calculator in Geometry?**

Aside from never having to worry about the use of pen and paper in making your illustrations in Geometry, you will save a lot of time in answering questions involving figures. With a calculator in your hand, you are one step ahead of those who do not have one.

**What to consider in buying a calculator**

It is necessary to know why and what calculator to buy. There are only three considerations in buying a calculator. These are Requirement, Features, and Price.

**Requirements**

You need to know what the purpose of your buying is and where to use it for. If you’re going to use it in a future test, then you have to check its approval to save yourself from double purchasing. If you’re going to use it in the class, you should ask your teacher.

**Features**

What makes calculators unique is that they may not be a daily essential but they sets a huge difference when needed. Considering the key features and functions of the graphing calculator you intend to buy should be aligned with the purpose of your buying.

#### **Price**

** **Price may be the underestimated or primary consideration that you may take. Either way, with the variety of calculators available in the market, you have to know the capability of your pocket and make some good use of your ability to research.
