A parallelogram is a quadrilateral with opposite sides parallel. You can use this percentile calculator to efficiently determine the p-th percentile for a set of numbers. Note: this uses Gram Schmidt orthogonalization which is numerically unstable. For example, one use of it is to prove the formula of volume in terms of Cayler Menger determinant (the generalization of Heron's formula for area of triangle). So the area of your parallelogram squared is equal to the determinant of the matrix whose column vectors construct that parallelogram. The Gram-Schmidt orthogonalization Orthogonal sets.

(TODO: implement these alternative methods) Determinant is a very useful value in linear algebra. The determinant formula for the Gram-Schmidt is computationally slower (exponentially slower) than the recursive algorithms described above; it is mainly of theoretical interest. Calculations include side lengths, corner angles, diagonals, height, perimeter and area of parallelograms. You can use the view menu button to add fuctionality to the standard calculator.
