About Us
Geometry Formulas is a free study site for geometry. We put every common formula in one place, show what each letter means and work through a real example, so you can solve the problem in front of you and move on.
What You Will Find Here
- Area and perimeter formulas for flat shapes
- Volume and surface area formulas for solids
- Triangle, trigonometry, circle and coordinate formulas
- Clear labeled diagrams we draw ourselves
- Free one-page PDF sheets you can print
Who It Is For
Middle school and high school students, parents helping with homework, teachers who want a quick reference, and anyone preparing for the SAT, ACT or GRE. If you need to measure a room, a garden bed or a concrete slab, the formulas work for that too.
How We Write Our Pages
- Every formula is checked against standard math textbooks.
- Every worked example is solved by hand and checked a second time.
- Test details, such as what is on the SAT reference sheet, come from official test makers and are dated.
- We use short sentences and plain words. No sign-up, no paywall.
