Q:
# What are some popular geometry calculators?

**Popular online geometry calculators are located on websites such as CalculatorSoup.com, AnalyzeMath.com and Basic-Mathematics.com.** These sites help solve geometric equations by computing an answer from values input by a student.

For example, the Pythagorean Theorem calculator found on Basic-Mathematics.com computes the hypotenuse, or longest side, of a right triangle when the user enters values for the shorter two sides. The site uses the a2 + b2 = c2 formula known as the Pythagorean formula to solve for “c” when values are entered for “a” and “b”. The site also features a calculator that determines the circumference of a circle when the radius is input.

Other calculators are available to help solve problems such as determining the area of a rectangle or the volume of a cylinder, to name a few. Calculators for trigonometry and algebra are also available on many of these sites. Geometry calculators can also be downloaded to computers as PC software or installed on mobile devices as an app.
