Question

why is the diameter of circle on the diagonal of rectangle if rectangle is inscribed in a circle

Answer 1

Dear student

For a rectangle, each angle is 90 degree

For a circle, angle in a semicircle is ​90 degree or converesely if the angle formed by a line at the segment is 90 degree, that line is then the diameter of the circle

For a rectangle, the diagonal forms a 90 degree at the segment of the circle, hence the diagonal is the diameter of the circle
