list of all geometry theorems?

[nazlysaey]

can somebody please reply with a list of all geometry theorems (phythagore, 5-12-13 triangle sides rule...etc) that we could ever need to solve geometry questions

Thanks a lot!

Check out the GMAT Math Study sheet. It contains all the formulas needed for the test.

I know I'm digging up an old post here, but the above link goes to nothing....

So, does anybody happen to have a list of all the geometry theorems we could possibly see on the test?

When I get a geometry data sufficiency problem wrong on a practice CAT it is usually because of some theorem I didn't remember...

Here’s a compact list of key geometry theorems you’ll commonly need: Pythagorean Theorem (and special right triangles 45-45-90, 30-60-90, 5-12-13), Triangle Sum Theorem, Exterior Angle Theorem, Isosceles Triangle Theorem, Similarity Theorems (AA, SAS, SSS), Triangle Inequality, Heron’s Formula, Area formulas (triangle ½bh, equilateral √3/4 a²), Law of Sines, Law of Cosines, Midsegment Theorem, Angle Bisector Theorem, Ceva’s and Menelaus’ Theorems, Parallel Line angle theorems, Polygon interior/exterior angle sums, Circle Theorems (inscribed angle, central angle, tangent–secant, chord theorems), Power of a Point, Thales’ Theorem, Coordinate geometry distance/midpoint/slope formulas, and basic transformations (reflection, rotation, translation, dilation).
