Question

Диагонали прямоугольника abcd при пересечение образуют угол=90° доказать что abcd квадрат. если не сложно, то напишите с дано.

Answer 1

Здесь не нужно "дано".
Согласно теореме, при пересечении диагоналей квадрата, они образуют уголовное = 90 градусов.
Вот и все.

Answer 2

Given Information

- Given: The diagonals of rectangle ABCD form a 90° angle.

Proof

To prove that ABCD is a square, we can use the properties of rectangles and squares. In a rectangle, the diagonals are equal in length, and they bisect each other at right angles. If we can show that the sides of the rectangle are also equal, then we can conclude that ABCD is a square.

Let's consider the properties of rectangles and squares: - In a rectangle, the diagonals are equal in length and bisect each other at right angles. - In a square, all sides are equal in length, and the diagonals bisect each other at right angles.

Explanation

Given that the diagonals of rectangle ABCD form a 90° angle, we can use this information to prove that ABCD is a square.

We know that in a rectangle, the diagonals are equal in length. If we can show that the sides of the rectangle are also equal, then we can conclude that ABCD is a square.

Let's denote the diagonals as AC and
