Về bài toán tính khoảng cách từ một điểm đến mặt phẳng trong hình học không gian

Abstract

In this article, we systematize different problem-solving approaches to calculating distances from one point to a space plane: point-deduction technique, twice-volume method, vector method and coordinate one, together with specific examples provided for each case to offer students with different perspectives on methods to solve this type of math problems.
