- Pythagorean Theorem: a² + b² = c², where a and b are the lengths of the two shorter sides of a right triangle, and c is the length of the hypotenuse.
- Volume of a cylinder = π * radius² * height
- Circumference of a circle = 2 * π * radius or π * diameter
- Area of a circle = π * radius²
- Volume of a sphere = (4/3) * π * radius³
- Surface area of a sphere = 4 * π * radius²
- Slope-intercept form of the equation of a line: y = mx + b, where m is the slope and b is the y-intercepts.
- Distance formula: √ ((x2 - x1) ² + (y2 - y1) ²), where (x1, y1) and (x2, y2) are the coordinates of two points in a coordinate plane.
- Midpoint formula: (x1 + x2)/2, (y1 + y2)/2), where (x1, y1) and (x2, y2) are the coordinates of two points in a coordinate plane.
To do well on the GRE geometry problems, you need more than just memorization of formulae. Candidates should not only know the formulae, but also how to use them to answer a variety of geometry questions in the test.

GRE Geometry Fomula's Rules
Geometry formulas for GRE are one of the most significant parts of the preparation for GRE geometry preparation. Following the fuels for applying the formula can aid in a high score. You need to have a proper GRE preparation time is very necessary as it will enable you to have an organized preparation and enough time.
- The Pythagorean Theorem states that the length of the hypotenuse (the side opposite the right angle) squared is equal to the sum of the squares of the other two sides. where c is the hypotenuse and a, b, and c are the side lengths of the triangle.
- What is the area of a triangle? The area of a triangle is equal to half the product of its base and height. A = 1/2 bh.
- The formula for the surface area of a circle is r2, where it is around 14, for a given radius r.
- The formula for the circumference of a circle is 2r, where r is the radius.
- The formula for a cylinder's volume is (r2) (h2), where r and h are the cylinder's radius and height, respectively.
- The volume of a sphere with radius r is equal to 4/3r3.
- When the right angles and the right sides of two triangles are equal, we say that the triangles are comparable.
- It is said that two triangles are congruent if and only if their respective angles and sides are also congruent.
- A polygon with n sides with interior angles that, when added together, equal (n-2) x 180 degrees.
- All the outside angles of a polygon add up to 360 degrees, regardless of the number of sides it has.
- Angles formed by the intersection of a transversal with a pair of parallel lines are congruent. So, if and only if they are on the same side of the transversal and have the same corresponding interior and exterior angles.
- Angles that add up to 90 degrees are considered right angles.
- Angles that are added to others make a whole, called a supplementary angle, which is always 180 degrees.
- When two right angles are added together, they form a right angle.
Keep in mind that although memorizing these formulae and principles is helpful for the GRE geometry portion, geometry GRE practice questions are more critical.
